Description

Technology Field

[0001] The present invention relates to an organic electroluminescence element, an organic electroluminescence display device, and an electronic device. Background Technology

[0002] Organic electroluminescence devices (hereinafter referred to as "organic EL devices") are applied to full-color displays such as mobile phones and televisions. When voltage is applied to an organic EL device, holes are injected from the anode into the light-emitting layer, and electrons are injected from the cathode into the light-emitting layer. Then, in the light-emitting layer, the injected holes and electrons recombine to form excitons. At this time, according to the statistical rule of electron spin, singlet excitons are generated at a rate of 25%, and triplet excitons are generated at a rate of 75%.

[0003] For example, in Patent Documents 1, 2, and 3, considerations have been made to improve the performance of organic EL devices. The performance of organic EL devices includes, for example, brightness, emission wavelength, chromaticity, luminous efficiency, driving voltage, and lifespan. One of the challenges of organic EL devices is the reduction in light extraction efficiency. In particular, attenuation caused by reflection resulting from the difference in refractive index of adjacent layers is a major factor in reducing the light extraction efficiency of organic EL devices. To mitigate this effect, a configuration of an organic EL device having a layer made of a low refractive index material has been proposed. Prior art literature

Specific details for implementing the invention

[0077] [definition]

[0078] In this specification, the term hydrogen atom includes isotopes with different numbers of neutrons, namely protium, deuterium, and tritium.

[0079] In this specification, in the chemical structural formula, hydrogen atoms, i.e., light hydrogen atoms, deuterium atoms, or tritium atoms are bonded to the bondable positions where symbols such as "R" or "D" representing a deuterium atom are not specified.

[0080] In this specification, the ring-forming carbon number refers to the number of carbon atoms among the atoms constituting the ring itself of a compound having a structure in which atoms are bonded in a ring (e.g., monocyclic compounds, condensed-ring compounds, crosslinked compounds, carbon-coupled compounds, and heterocyclic compounds). When the ring is substituted by a substituent, the carbons included in the substituent are not included in the ring-forming carbon number. Unless otherwise noted, the "ring-forming carbon number" described below shall be the same. For example, the benzene ring has a ring-forming carbon number of 6, the naphthalene ring has a ring-forming carbon number of 10, the pyridine ring has a ring-forming carbon number of 5, and the furan ring has a ring-forming carbon number of 4. In addition, for example, the ring-forming carbon number of a 9,9-diphenylfluorenyl group is 13, and the ring-forming carbon number of a 9,9'-spirobifluorenyl group is 25.

[0081] In addition, when a benzene ring is substituted with, for example, an alkyl group, the number of carbon atoms of the alkyl group is not included in the number of carbon atoms forming the ring of the benzene ring. Therefore, the number of carbon atoms forming the ring of the benzene ring substituted with an alkyl group is 6. In addition, when a naphthalene ring is substituted with, for example, an alkyl group, the number of carbon atoms of the alkyl group is not included in the number of carbon atoms forming the ring of the naphthalene ring. Therefore, the number of carbon atoms forming the ring of the naphthalene ring substituted with an alkyl group is 10.

[0082] In this specification, the number of ring-forming atoms refers to the number of atoms constituting the ring itself of a compound having a structure in which atoms are bonded in a ring (e.g., a single ring, a condensed ring, and a ring assembly) (e.g., a single ring compound, a condensed ring compound, a crosslinked compound, a carbon ring compound, and a complex ring compound). Atoms that do not constitute a ring (e.g., a hydrogen atom terminating the bond of the atoms constituting the ring) or atoms included in the substituents when the ring is substituted by a substituent are not included in the number of ring-forming atoms. Unless otherwise noted, the "number of ring-forming atoms" described below shall be the same. For example, the number of ring-forming atoms of a pyridine ring is 6, the number of ring-forming atoms of a quinazolin ring is 10, and the number of ring-forming atoms of a furan ring is 5. For example, the number of hydrogen atoms bonded to a pyridine ring or the number of atoms constituting the substituents are not included in the number of ring-forming atoms of a pyridine ring. For this reason, the number of ring-forming atoms of a pyridine ring to which hydrogen atoms or substituents are bonded is 6. Also, for example, hydrogen atoms or atoms constituting substituents bonded to carbon atoms of a quinazoline ring are not included in the number of ring-forming atoms of the quinazoline ring. For this reason, the number of ring-forming atoms of a quinazoline ring to which hydrogen atoms or substituents are bonded is 10.

[0083] In the present specification, in the expression “substituted or unsubstituted ZZ group having XX to YY carbon atoms,” “XX to YY carbon atoms” indicates the number of carbon atoms when the ZZ group is unsubstituted and does not include the number of carbon atoms of the substituent when it is substituted. Here, “YY” is greater than “XX,” where “XX” means an integer of 1 or more, and “YY” means an integer of 2 or more.

[0084] In the present specification, the "number of atoms XX to YY" in the expression "ZZ group having XX to YY of substituted or unsubstituted atoms" represents the number of atoms when the ZZ group is unsubstituted and does not include the number of atoms of the substituent when it is substituted. Here, "YY" is greater than "XX," where "XX" means an integer greater than or equal to 1, and "YY" means an integer greater than or equal to 2.

[0085] In this specification, the term "unsubstituted ZZ group" indicates the case where the "substituted or unsubstituted ZZ group" is the "unsubstituted ZZ group," and the term "substituted ZZ group" indicates the case where the "substituted or unsubstituted ZZ group" is the "substituted ZZ group."

[0086] In this specification, when referring to a "substituted or unsubstituted ZZ group," "unsubstituted" means that the hydrogen atoms in the ZZ group are not substituted with substituents. The hydrogen atoms in the "unsubstituted ZZ group" are light hydrogen atoms, deuterium atoms, or tritium atoms.

[0087] In addition, in the present specification, "substitution" in the case of "substituted or unsubstituted ZZ group" means that one or more hydrogen atoms in the ZZ group are substituted with substituents. Likewise, "substitution" in the case of "BB group substituted with AA group" means that one or more hydrogen atoms in the BB group are substituted with AA groups.

[0466] · "When combined to form a ring"

[0467] In the present specification, the phrase “one or more of two or more adjacent groups combine to form a substituted or non-substituted ring, combine to form a substituted or non-substituted condensed ring, or do not combine to each other” means the case where “one or more of two or more adjacent groups combine to form a substituted or non-substituted ring,” the case where “one or more of two or more adjacent groups combine to form a substituted or non-substituted condensed ring,” and the case where “one or more of two or more adjacent groups do not combine to each other.”

An example is provided for an anthracene compound represented by the following general formula (TEMP-103), in which the matrix is ​​an anthracene ring.

[0469] [Chemical Formula 23]

The ring Q of the above general formula (TEMP-105) A and ring Q C is ring Q A and ring Q C It becomes a condensed ring through condensation. The ring Q of the above general formula (TMEP-104) A If is a benzene ring, then ring Q A is a single ring. The ring Q of the above general formula (TMEP-104)A If is a naphthalene ring, then ring Q A is a condensed ring.

[0479] "Unsaturated ring" refers to an aromatic hydrocarbon ring or an aromatic complex ring. "Saturated ring" refers to an aliphatic hydrocarbon ring or a non-aromatic complex ring.

[0482] As a specific example of an aliphatic hydrocarbon ring, a structure in which the group given as a specific example in the specific example group G6 is terminated by a hydrogen atom can be cited.

[0483] "Forming a ring" means forming a ring with only multiple atoms of the matrix or with multiple atoms of the matrix and one or more additional arbitrary elements. For example, R represented in the above general formula (TEMP-104). 921 and R 922 A ring Q formed by the combination of each other A is, R 921 The carbon atom of the anthracene skeleton that bonds with this, and R 922 It refers to a ring formed by a carbon atom of the anthracene skeleton to which it bonds, and one or more arbitrary elements.

In any element (e.g., in the case of a carbon or nitrogen element), bonds that do not form a ring may be terminated by a hydrogen atom or the like, or substituted by an "any substituent" described below. When any element other than a carbon element is included, the ring formed is a complex ring.

[0574] 0.30 < TL3 / TL2 < 5.0 … (Mathematical Formula A4)

[0575] (TL2 is the film thickness of the second anode-side organic layer, TL3 is the film thickness of the third anode-side organic layer, and the unit of film thickness is nm.)

[0576] The elements that an organic EL element of each embodiment of the present embodiment may have are described below. The first, second, third, fourth, and fifth embodiments described above are examples of embodiments that include one or more elements selected from the elements described below.

[0577] According to the present embodiment, the device performance of an organic EL device can be improved. In one aspect of the present embodiment, the luminous efficiency of the organic EL device is improved. In one aspect of the present embodiment, the organic EL device has a long lifespan.

[0578] By utilizing a layer made of a low-refractive-index material as an organic layer (e.g., a hole transport layer) in the hole transport band, light emission loss due to the evanescent mode can be reduced. Additionally, as an organic layer in the hole transport band (e.g., a hole transport layer), by placing an organic layer made of a high-refractive-index material on the anode side and an organic layer made of a low-refractive-index material on the emissive-layer side, light emission loss in the thin-film mode can be reduced. In particular, light extraction in a bottom-emission type organic electroluminescence device can simultaneously prevent light emission loss in the organic thin-film layer as well as light emission loss in the substrate mode, thereby further improving efficiency. In particular, if the film thickness of the organic layer made of a low-refractive-index material is 20 nm or more, the light extraction efficiency can be effectively increased. Furthermore, in the organic layer in the hole transport band, hole supply characteristics can be easily adjusted by combining two different types of materials.

[0579] (Precision Transport Band)

[0580] In this specification, a region consisting of a plurality of organic layers disposed between an anode and a light-emitting region may be referred to as a hole transport band.

[0581] In one embodiment of the organic EL device of the present embodiment, the ratio TL3 / TL2 of the film thickness TL2 of the second anode-side organic layer and the film thickness TL3 of the third anode-side organic layer satisfies a predetermined relationship.

[0582] In one embodiment of the organic EL device of the present embodiment, the ratio of the film thickness of the second anode-side organic layer to the film thickness of the third anode-side organic layer satisfies the relationship of the following formula (Formula A1), formula (Formula A2), formula (Formula A3), or formula (Formula A4).

[0583] 0.50 < TL3 / TL2 < 4.0 … (Mathematical Formula A1)

[0584] 0.30 < TL3 / TL2 < 4.0 … (Mathematical Formula A2)

[0585] 0.75 < TL3 / TL2 < 3.0 … (Mathematical Formula A3)

[0586] 0.30 < TL3 / TL2 < 5.0 … (Mathematical Formula A4)

[0587] (TL2 is the film thickness of the second anode-side organic layer, TL3 is the film thickness of the third anode-side organic layer, and the unit of film thickness is nm.)

[0588] In one embodiment of the organic EL device of the present embodiment, the non-TL3 / TL2 is 1 or more.

[0589] In one embodiment of the organic EL device of the present embodiment, the ratio TL3 / TL2 is 2.5 or less.

[0590] In one embodiment of the organic EL device of the present embodiment, the sum of the film thickness of the second anode-side organic layer and the film thickness of the third anode-side organic layer is 30 nm or more, 70 nm or more, or 100 nm or more.

[0591] In the organic EL device of the present embodiment, it is believed that the excitation energy of the emitting layer can be prevented from moving to the hole transport band by making the film thickness of the organic layer of the hole transport band disposed on the anode side of the emitting region large (e.g., the sum of the film thickness of the second anode-side organic layer and the film thickness of the third anode-side organic layer is 30 nm or more), and by making the ratio of the film thickness of the second anode-side organic layer to the film thickness of the third anode-side organic layer within a predetermined range (e.g., within the range of the above formula (Equation A1), Equation A2), Equation A3, or Equation A4). It is believed that by preventing the movement of the excitation energy of the emitting layer, the luminous efficiency of the organic EL device is improved.

[0592] In one embodiment of the organic EL device of the present embodiment, the sum of the film thickness of the second anode-side organic layer and the film thickness of the third anode-side organic layer is 150 nm or less.

[0594] In one embodiment of the organic EL device of the present embodiment, the film thickness of the third anode-side organic layer is 15 nm or more or 20 nm or more.

[0595] It is thought that by having a film thickness of 15 nm or more of the third anode-side organic layer, the third anode-side organic layer becomes more effective in preventing the transfer of excitation energy of the light-emitting layer.

[0596] In one embodiment of the organic EL device of the present embodiment, the film thickness of the third anode-side organic layer is 80 nm or less, 75 nm or less, or 60 nm or less.

[0597] From the perspective of improving light extraction efficiency, the film thickness of the third anode-side organic layer is preferably 15 nm or more and 75 nm or less, and more preferably 20 nm or more and 60 nm or less.

[0598] In one aspect of the organic EL device of the present embodiment, the difference NM2-NM3 between the refractive index NM2 of the constituent material included in the second anode-side organic layer and the refractive index NM3 of the constituent material included in the third anode-side organic layer satisfies the relationship of the following formula (Equation N1). The refractive index NM2 of the constituent material included in the second anode-side organic layer corresponds to the refractive index of said one compound when the second anode-side organic layer contains said one compound, and corresponds to the refractive index of said mixture containing said multiple compounds when the second anode-side organic layer contains said multiple compounds. The refractive index NM3 of the constituent material included in the third anode-side organic layer is also defined in the same way as the refractive index NM2 of the constituent material included in the second anode-side organic layer. The refractive index can be measured by the measurement method described in the example to be described later. In this specification, the refractive index at 2.7 eV in the substrate parallel direction (ordinary direction) measured by multi-angle incident spectroscopic ellipsometry is defined as the refractive index of the material being measured. The refractive index at 2.7 eV corresponds to the refractive index at 460 nm.

[0599] NM2 - NM3 ≥ 0.05 … (Mathematical formula N1)

[0600] By satisfying the relationship of the above formula (mathematical formula N1), the light extraction efficiency of the organic EL device is improved.

[0601] In one embodiment of the organic EL device of the present embodiment, the difference NM2-NM3 between the refractive index NM2 of the constituent material included in the second anode-side organic layer and the refractive index NM3 of the constituent material included in the third anode-side organic layer satisfies the relationship of the following formula (formula N2) or (formula N3).

[0602] NM2 - NM3 ≥ 0.10 … (Mathematical formula N2)

[0603] NM2 - NM3 ≥ 0.075 … (Mathematical formula N3)

[0604] In this specification, the refractive index at 2.7 eV (460 nm) in the substrate parallel direction (ordinary direction) is n ORD denoted as , and the refractive index at 2.7 eV (460 nm) in the direction perpendicular to the substrate (extra-ordinary direction) is n EXT There are cases where it is written as .

[0605] In one embodiment of the organic EL device of the present embodiment, the refractive index n at 460 nm of the constituent material included in the second anode-side organic layer ORD and refractive index n EXT The difference n ORD -n EXT It is desirable that it be 0.1 or higher.

[0606] In one embodiment of the organic EL device of the present embodiment, the refractive index of the compound contained in the second anode-side organic layer is 1.94 or higher.

[0607] In one embodiment of the organic EL device of the present embodiment, the refractive index of the compound contained in the third anode-side organic layer is 1.89 or less.

[0608] In one embodiment of the organic EL device of the present embodiment, the distance from the anode-side interface of the third anode-side organic layer to the anode-side interface of the light-emitting layer disposed on the anode side of the light-emitting region is 20 nm or more.

[0609] By having a distance of 20 nm or more from the anode-side interface of the third anode-side organic layer to the anode-side interface of the light-emitting layer positioned closest to the anode in the light-emitting region, it becomes easier to improve light extraction efficiency.

[0610] The distance from the anode-side interface of the third anode-side organic layer to the anode-side interface of the light-emitting layer positioned at the most anode side in the light-emitting region is, for example, equivalent to the film thickness of the third anode-side organic layer in the case where the third anode-side organic layer is in direct contact with the second anode-side organic layer on the anode side and in direct contact with the light-emitting layer positioned at the most anode side in the light-emitting region on the cathode side.

[0611] In addition, the distance from the anode-side interface of the third anode-side organic layer to the anode-side interface of the light-emitting layer positioned at the anode side of the light-emitting region is, for example, equivalent to the total film thickness of the third anode-side organic layer and the fourth anode-side organic layer, in the case where the third anode-side organic layer is in direct contact with the second anode-side organic layer on the anode side and in direct contact with the fourth anode-side organic layer described later on the cathode side, and the fourth anode-side organic layer is in direct contact with the light-emitting layer positioned at the anode side of the light-emitting region on the cathode side.

[0612] In one embodiment of the organic EL device of the present embodiment, the distance from the anode-side interface of the third anode-side organic layer to the anode-side interface of the light-emitting layer positioned at the anode side of the light-emitting region is 30 nm or more.

[0613] In one embodiment of the organic EL device of the present embodiment, the third anode-side organic layer contains a compound represented by the general formula (C1) or a compound represented by the general formula (C2).

[0614] In one embodiment of the organic EL device of the present embodiment, the first anode-side organic layer, the second anode-side organic layer, and the third anode-side organic layer each comprise one or more different compounds.

[0615] In one embodiment of the organic EL device of the present embodiment, the first anode-side organic layer and the second anode-side organic layer may both contain a compound represented by the general formula (C1) or a compound represented by the general formula (C2), but the compounds contained in the first anode-side organic layer and the second anode-side organic layer have different molecular structures from the compounds contained in the third anode-side organic layer.

[0616] In one embodiment of the organic EL device of the present embodiment, the compounds contained in the second anode-side organic layer are all different from the compounds contained in the third anode-side organic layer.

[0617] An example of an embodiment satisfying this condition is that the second anode-side organic layer contains one type of compound AA and the third anode-side organic layer contains one type of compound BB.

[0618] In addition, for example, even if the second anode-side organic layer contains two types of compounds AA and AB and the third anode-side organic layer contains one type of compound BB, the above conditions are satisfied because compounds AA and AB are both different from compound BB. Compounds AA, AB, and BB are different compounds from each other.

[0619] On the other hand, for example, if the second anode-side organic layer contains two types of compounds AA and AB, and the third anode-side organic layer contains one type of compound AB, the above conditions are not satisfied because the second anode-side organic layer and the third anode-side organic layer contain the same compound with respect to compound AB.

[0620] In one embodiment of the organic EL device of the present embodiment, the third anode-side organic layer contains a third hole transport band material. The compound contained in the third anode-side organic layer may be referred to as the third hole transport band material.

[0621] In one aspect of the organic EL device of the present embodiment, the hole mobility μh (cHT3) of the third hole transport band material is 1.0 × 10⁻⁶ -5 cm 2 It is greater than / Vs.

If the hole mobility μh(cHT3) and HOMO(cHT3) of the third hole transport band material are in this range, the hole mobility of the third anode-side organic layer is high, and the hole injection into the emissive layer in the emission region is also high.

[0624] In one embodiment of the organic EL device of the present embodiment, the singlet energy of the third hole transport band material is greater than 3.12 eV.

[1563] In one embodiment of the organic EL device of the present embodiment, the light-emitting region consists of only one light-emitting layer.

[1564] In one embodiment of the organic EL device of the present embodiment, the light-emitting region includes a first light-emitting layer and a second light-emitting layer as two light-emitting layers.

[1565] In one embodiment of the organic EL device of the present embodiment, the light-emitting region consists of only two light-emitting layers.

[1566] In the organic EL device according to the present embodiment, it is preferable that the light-emitting layer contains a light-emitting compound. The light-emitting compound is not particularly limited, but may contain at least one light-emitting compound selected from the group consisting of the first light-emitting compound and the second light-emitting compound described below, for example. In the organic EL device according to the present embodiment, it is preferable that the light-emitting layer contains the light-emitting compound in an amount of 0.5 mass% or more of the total mass of the light-emitting layer. It is preferable that the light-emitting layer contains the light-emitting compound in an amount of 10 mass% or less of the total mass of the light-emitting layer, more preferable that it contains 7 mass% or less of the total mass of the light-emitting layer, and even more preferable that it contains 5 mass% or less of the total mass of the light-emitting layer.

[1567] In one embodiment of the organic EL device of the present embodiment, at least one light-emitting layer in the light-emitting region contains a light-emitting compound that exhibits light emission with a maximum peak wavelength of 500 nm or less. In one embodiment of the organic EL device of the present embodiment, the maximum peak wavelength of light emission exhibited by the light-emitting compound is 480 nm or less. In one embodiment of the organic EL device of the present embodiment, the maximum peak wavelength of light emission exhibited by the light-emitting compound is 430 nm or more and 480 nm or less.

[1568] In one embodiment of the organic EL device of the present embodiment, at least one light-emitting layer in the light-emitting region contains a light-emitting compound that exhibits fluorescent light emission with a maximum peak wavelength of 500 nm or less. In one embodiment of the organic EL device of the present embodiment, the maximum peak wavelength of the fluorescent light emission exhibited by the light-emitting compound is 480 nm or less. In one embodiment of the organic EL device of the present embodiment, the maximum peak wavelength of the fluorescent light emission exhibited by the light-emitting compound is 430 nm or more and 480 nm or less.

[1569] In the organic EL device according to the present embodiment, it is also preferable that the light-emitting region has at least a first light-emitting layer containing a first host material and a second light-emitting layer containing a second host material. The first host material and the second host material are different from each other.

[1570] In the present specification, the “host material” is a material that is included, for example, in “50 mass% or more of the layer.” Accordingly, for example, the first light-emitting layer contains the first host material in 50 mass% or more of the total mass of the first light-emitting layer. Also, for example, the second light-emitting layer contains the second host material in 50 mass% or more of the total mass of the second light-emitting layer. Additionally, for example, the “host material” may be included in 60 mass% or more of the layer, 70 mass% or more of the layer, 80 mass% or more of the layer, 90 mass% or more of the layer, or 95 mass% or more of the layer.

[1571] It is desirable that the triplet energy T1 (H1) of the first host material and the triplet energy T1 (H2) of the second host material satisfy the relationship of the following formula (Equation 1).

[1572] T1(H1) > T1(H2) … (Equation 1)

[1573] In the organic EL device according to the present embodiment, it is preferable that the triplet energy T1 (H1) of the first host material and the triplet energy T1 (H2) of the second host material satisfy the relationship of the following formula (Equation 5).

[1574] T1(H1) - T1(H2) > 0.03 eV … (Equation 5)

[1575] The organic EL device according to the present embodiment can improve the luminous efficiency of the device when it has a first light-emitting layer and a second light-emitting layer that satisfy the relationship of the above formula (Equation 1).

[1576] Conventionally, Triplet-Triplet-Annhilation (sometimes referred to as TTA) is known as a technique for improving the luminescence efficiency of organic electroluminescence devices. TTA is a mechanism in which triplet excitons collide to generate singlet excitons. Additionally, the TTA mechanism is sometimes referred to as the TTF mechanism, as described in International Publication No. 2010 / 134350.

[1577] The TTF phenomenon is explained. Holes injected from the anode and electrons injected from the cathode recombine within the emissive layer to generate excitons. As is conventionally known, the spin states consist of 25% singlet excitons and 75% triplet excitons. In conventional fluorescent devices, light is emitted when 25% of the singlet excitons relax to the ground state, but the remaining 75% of the triplet excitons do not emit light and return to the ground state through a thermal deactivation process. Therefore, the theoretical limit of the internal quantum efficiency of conventional fluorescent devices is stated to be 25%.

[1578] Meanwhile, the behavior of triplet excitons generated within organic matter is being theoretically investigated. According to the literature [SM Bachilo et al., J. Phys. Chem. A, 104, 7711(2000)], assuming that higher-order excitons such as pentatons immediately revert to triplets, triplet excitons (hereinafter, 3 When the density of (represented as A*) increases, triplet excitons collide with each other, and a reaction as shown in the following equation occurs. Here, 1 A represents the ground state, and 1 A* represents the lowest excitation singlet exciton.

[1579] 3 A*+ 3 A*→(4 / 9) 1 A+(1 / 9) 1 A*+(13 / 9) 3 A*

[1580] That is, 5 3 A*→4 1It is predicted that A+1A*, and that 1 / 5, or 20%, of the 75% of triplet excitons initially generated will be converted into singlet excitons. Therefore, the singlet excitons contributing as light are said to be 40%, which is the sum of 25% of the initially generated singlet excitons plus 75% × (1 / 5) = 15%. At this time, the proportion of TTF-derived light (TTF ratio) in the total light intensity is 15 / 40, or 37.5%. Furthermore, if the 75% of triplet excitons initially generated collide with each other to generate singlet excitons (one singlet exciton is generated from two triplet excitons), a very high internal quantum efficiency of 62.5% can be obtained, which is the sum of 25% of the initially generated singlet excitons plus 75% × (1 / 2) = 37.5%. At this time, the TTF ratio is 37.5 / 62.5=60%.

[1581] In the case where the light-emitting region of the organic EL device according to the present embodiment has at least two light-emitting layers (i.e., a first light-emitting layer and a second light-emitting layer) and the triplet energy T1 (H1) of the first host material in the first light-emitting layer and the triplet energy T1 (H2) of the second host material in the second light-emitting layer satisfy the relationship of the above formula (Equation 1), it is thought that triplet excitons generated by the recombination of holes and electrons in the first light-emitting layer are difficult to quench even if there is an excess of carriers at the interface between the first light-emitting layer and the organic layer that is in direct contact with the first light-emitting layer. For example, if the recombination region exists locally at the interface between the first light-emitting layer and the hole transport layer or the electron barrier layer, quenching by excess electrons can be considered. On the other hand, if the recombination region exists locally at the interface between the first light-emitting layer and the electron transport layer or the hole barrier layer, quenching by excess holes can be considered.

[1582] By providing a first light-emitting layer and a second light-emitting layer to satisfy the relationship of the above formula (Mathematical Formula 1), triplet excitons generated in the first light-emitting layer move to the second light-emitting layer without being quenched by excess carriers, and also suppress reverse movement from the second light-emitting layer to the first light-emitting layer. As a result, in the second light-emitting layer, the TTF mechanism is expressed, singlet excitons are efficiently generated, and the light-emitting efficiency is improved.

[1583] In this way, the organic EL device according to the present embodiment has a first light-emitting layer that mainly generates triplet excitons and a second light-emitting layer that mainly expresses a TTF mechanism by utilizing triplet excitons moved from the first light-emitting layer as different regions, and as a second host material in the second light-emitting layer, a compound having a triplet energy smaller than that of the first host material in the first light-emitting layer is used to set a difference in triplet energy, thereby improving the light-emitting efficiency.

[1584] In the organic EL device according to the present embodiment, it is preferable that the first light-emitting layer is disposed between the anode and the cathode, and the second light-emitting layer is disposed between the first light-emitting layer and the cathode. From the anode side, the first light-emitting layer and the second light-emitting layer may be arranged in this order, or from the anode side, the second light-emitting layer and the first light-emitting layer may be arranged in this order. In either case, by selecting a combination of materials that satisfies the relationship of the above formula (Equation 1), the effect of the light-emitting layer being a stacked configuration can be expected.

[1585] In the organic EL device according to the present embodiment, it is also preferable that the first light-emitting layer is positioned on the positive side rather than the second light-emitting layer.

[1592] (1st light-emitting layer)

[1593] The first light-emitting layer comprises a first host material. The first host material is a compound different from the second host material contained in the second light-emitting layer.

[1594] The first emitting layer preferably comprises a first emitting compound. The first emitting compound is not particularly limited. The first emitting compound is preferably a compound exhibiting luminescence with a maximum peak wavelength of 500 nm or less, more preferably a compound exhibiting luminescence with a maximum peak wavelength of 480 nm or less, and even more preferably a compound exhibiting luminescence with a maximum peak wavelength of 430 nm or more and 480 nm or less. The first emitting compound is preferably a fluorescent emitting compound exhibiting fluorescent luminescence with a maximum peak wavelength of 500 nm or less, more preferably a fluorescent emitting compound exhibiting fluorescent luminescence with a maximum peak wavelength of 480 nm or less, and even more preferably a fluorescent emitting compound exhibiting fluorescent luminescence with a maximum peak wavelength of 430 nm or more and 480 nm or less.

[1595] In the organic EL device according to the present embodiment, the first luminescent compound is preferably a compound that does not contain a zygos ring structure in its molecule.

[1596] In the organic EL device according to the present embodiment, it is preferable that the first luminescent compound is not a boron-containing complex, and it is more preferable that the first luminescent compound is not a complex.

[1597] As a fluorescently emitting compound that emits blue light and can be used in the first light-emitting layer, a compound selected from the group consisting of, for example, pyrene derivatives, styrylamine derivatives, chrysene derivatives, fluoranthene derivatives, fluorene derivatives, diamine derivatives, and triarylamine derivatives may be used.

[1598] In this specification, blue light emission refers to light emission in which the maximum peak wavelength of the emission spectrum is within the range of 430 nm or more and 500 nm or less.

[1599] In the organic EL device according to the present embodiment, it is preferable that the first light-emitting layer does not contain a metal complex. In addition, in the organic EL device according to the present embodiment, it is also preferable that the first light-emitting layer does not contain a boron-containing complex.

[1600] In the organic EL device according to the present embodiment, it is preferable that the first light-emitting layer does not include a phosphorescent light-emitting material (dopant material).

[1601] In addition, it is preferable that the first light-emitting layer does not include heavy metal complexes and phosphorescent rare earth metal complexes. Here, examples of heavy metal complexes include iridium complexes, osmium complexes, and platinum complexes.

[1602] The method for measuring the maximum peak wavelength of a compound is as follows. A 5 μmol / L toluene solution of the compound to be measured is prepared and placed in a quartz cell, and the emission spectrum of the sample (vertical axis: emission intensity, horizontal axis: wavelength) is measured at room temperature (300 K). The emission spectrum can be measured using a spectrofluorescence photometer manufactured by Hitachi High-Tech Science Co., Ltd. (device name: F-7000). Furthermore, the emission spectrum measuring device is not limited to the device used herein.

[1603] In the emission spectrum, the peak wavelength of the emission spectrum where the emission intensity is maximum is defined as the maximum peak wavelength. Additionally, in this specification, the maximum peak wavelength of fluorescence emission may be referred to as the fluorescence emission maximum peak wavelength (FL-peak).

[1604] In the emission spectrum of the first luminescent compound, the peak at which the emission intensity is maximum is set as the maximum peak, and when the height of the maximum peak is set to 1, it is preferable that the height of other peaks appearing in the emission spectrum is less than 0.6. In addition, the peaks in the emission spectrum are set to maximum values.

[1605] In addition, it is preferable that the number of peaks in the emission spectrum of the first luminescent compound is less than 3.

[1606] In the organic EL device according to the present embodiment, it is preferable that the singlet energy S1 (H1) of the first host material and the singlet energy S1 (D1) of the first luminescent compound satisfy the relationship of the following formula (Equation 20).

[1607] S1(H1) > S1(D1) … (Equation 20)

[1608] Singlet energy S1 refers to the energy difference between the lowest excited singlet state and the ground state.

[1609] By satisfying the relationship of the first host material and the first luminescent compound in the formula (Equation 20), the singlet excitons generated on the first host material become more likely to transfer energy from the first host material to the first luminescent compound, thereby contributing to the fluorescent emission of the first luminescent compound.

[1610] In the organic EL device according to the present embodiment, it is desirable that the triplet energy T1 (H1) of the first host material and the triplet energy T1 (D1) of the first luminescent compound satisfy the relationship of the following formula (Equation 20A).

[1611] T1(D1) > T1(H1) … (Equation 20A)

[1612] As the first host material and the first luminescent compound satisfy the relationship of Equation (Equation 20A), the triplet excitons generated within the first luminescent layer move on the first host material phase rather than the first luminescent compound having a higher triplet energy, making it easier for them to move to the second luminescent layer.

[1613] The organic EL device according to the present embodiment preferably satisfies the relationship of the following formula (Equation 20B).

[1614] T1(D1) > T1(H1) > T1(H2) … (Equation 20B)

[1615] (Triplet energy T1)

[1616] The following methods can be used to measure the triplet energy T1.

[1617] The compound to be measured in EPA (diethyl ether:isopentane:ethanol = 5:5:2 (volume ratio)), 10 -5 mol / L or more 10 -4 A solution is prepared by dissolving to a concentration of mol / L or less, and this solution is placed in a quartz cell to serve as the measurement sample. For this measurement sample, the phosphorescence spectrum (vertical axis: phosphorescence emission intensity, horizontal axis: wavelength) is measured at a low temperature (77 K). A tangent line is drawn along the rising short-wavelength side of the phosphorescence spectrum, and the wavelength value λ at the intersection of the tangent line and the horizontal axis is... edge Based on [nm], the amount of energy calculated from the following conversion formula (F1) is called the triplet energy T1.

[1618] Conversion formula (F1): T1[eV]=1239.85 / λ edge

[1619] The tangent line for the rise on the short-wavelength side of the phosphorescence spectrum is drawn as follows. When moving along the spectrum curve from the short-wavelength side of the phosphorescence spectrum to the shortest maximum value among the maximum values ​​of the spectrum, the tangent line at each point on the curve toward the long-wavelength side is considered. As the curve rises (i.e., as the vertical axis increases), the slope of this tangent line increases. The tangent line drawn at the point where this slope takes a maximum value (i.e., the tangent line at the inflection point) is designated as the tangent line for the rise on the short-wavelength side of the phosphorescence spectrum.

[1620] In addition, the maximum point having a peak intensity of 15% or less of the maximum peak intensity of the spectrum is not included in the maximum value on the shortest wavelength side mentioned above, and the tangent line drawn from the point where the slope value closest to the maximum value on the shortest wavelength side takes a maximum value is the tangent line for the rise on the short wavelength side of the phosphorescent spectrum.

[1621] For the measurement of phosphorescence, the main body of the F-7000 spectrofluorescence photometer manufactured by Hitachi High-Tech Science Inc. or the main body of the F-4500 spectrofluorescence photometer manufactured by Hitachi High-Tech Inc. may be used. In addition, the measuring device is not limited thereto, and measurement may be performed by combining a cooling device, a low-temperature container, an excitation light source, and a light receiving device.

[1622] (Singlet energy S1)

[1623] The following methods can be used as methods for measuring the singlet energy S1 using a solution (sometimes called the solution method).

[1624] 10 of the compound to be measured -5 mol / L or more 10 -4 Prepare a toluene solution with a mol / L or lower content, place it in a quartz cell, and measure the absorption spectrum of the sample at room temperature (300 K) (vertical axis: absorption intensity, horizontal axis: wavelength). Draw a tangent line to the descent on the long-wavelength side of this absorption spectrum, and the wavelength value λ at the intersection of the tangent line and the horizontal axis.edge The singlet energy is calculated by substituting [nm] into the conversion formula (F2) shown below.

[1625] Conversion formula (F2): S1[eV]=1239.85 / λ edge

[1626] As an absorption spectrum measuring device, for example, a spectrophotometer manufactured by Hitachi (device name: U3310) can be cited, but is not limited to this.

[1627] The tangent line for the descent on the long-wavelength side of the absorption spectrum is drawn as follows. Consider the tangent line at each point on the spectrum curve when moving along the long-wavelength direction from the maximum value on the longest wavelength side among the maximum values ​​of the absorption spectrum. As the curve descends (i.e., as the value of the vertical axis decreases), the slope of this tangent line repeatedly decreases and then increases. The tangent line drawn at the point where the slope value takes a minimum value on the longest wavelength side (except when the absorbance becomes 0.1 or less) is defined as the tangent line for the descent on the long-wavelength side of the absorption spectrum.

[1628] In addition, maximum points with an absorbance value of 0.2 or less are not included in the maximum values ​​on the longest wavelength side.

[1629] In the organic EL device according to the present embodiment, it is preferable that the first light-emitting layer contains at least 0.5 mass% of the first light-emitting compound of the total mass of the first light-emitting layer.

[1630] The first light-emitting layer preferably contains the first light-emitting compound in an amount of 10 mass% or less of the total mass of the first light-emitting layer, more preferably contains 7 mass% or less of the total mass of the first light-emitting layer, and even more preferably contains 5 mass% or less of the total mass of the first light-emitting layer.

[1631] In an organic EL device according to the present embodiment, the first light-emitting layer preferably contains a first compound as a first host material in an amount of 60 mass% or more of the total mass of the first light-emitting layer, more preferably contains 70 mass% or more of the total mass of the first light-emitting layer, even more preferably contains 80 mass% or more of the total mass of the first light-emitting layer, even more preferably contains 90 mass% or more of the total mass of the first light-emitting layer, and even more preferably contains 95 mass% or more of the total mass of the first light-emitting layer.

[1632] It is preferable that the first light-emitting layer contains the first host material in an amount of 99.5 mass% or less of the total mass of the first light-emitting layer.

[1633] However, if the first light-emitting layer contains a first host material and a first light-emitting compound, the upper limit of the total content of the first host material and the first light-emitting compound is 100 mass%.

[1634] In the organic EL device according to the present embodiment, the film thickness of the first light-emitting layer is preferably 3 nm or more, and more preferably 5 nm or more. If the film thickness of the first light-emitting layer is 3 nm or more, it is a sufficient film thickness to cause recombination of holes and electrons in the first light-emitting layer.

If the film thickness of the first light-emitting layer is 15 nm or less, it is a sufficiently thin film thickness for triplet excitons to move to the second light-emitting layer.

[1636] In the organic EL device according to the present embodiment, it is more preferable that the film thickness of the first light-emitting layer is 3 nm or more and 15 nm or less.

The second emitting compound is preferably a compound exhibiting luminescence with a maximum peak wavelength of 500 nm or less, more preferably a compound exhibiting luminescence with a maximum peak wavelength of 480 nm or less, and even more preferably a compound exhibiting luminescence with a maximum peak wavelength of 430 nm or more and 480 nm or less. The second emitting compound is preferably a fluorescent emitting compound exhibiting fluorescent luminescence with a maximum peak wavelength of 500 nm or less, more preferably a fluorescent emitting compound exhibiting fluorescent luminescence with a maximum peak wavelength of 480 nm or less, and even more preferably a fluorescent emitting compound exhibiting fluorescent luminescence with a maximum peak wavelength of 430 nm or more and 480 nm or less.

[1640] The method for measuring the maximum peak wavelength of a compound is as described above.

[1641] In the organic EL device according to the present embodiment, it is preferable that the second light-emitting layer emits light having a maximum peak wavelength of 500 nm or less when the device is driven.

[1642] In the organic EL device according to the present embodiment, it is preferable that the full width at half maximum of the second luminescent compound is 1 nm or more and 20 nm or less.

[1643] In the organic EL device according to the present embodiment, it is preferable that the Stokes shift of the second luminescent compound exceeds 7 nm.

[1644] If the Stokes shift of the second luminescent compound exceeds 7 nm, it becomes easier to prevent a decrease in luminescence efficiency due to self-absorption.

[1645] Self-absorption is a phenomenon in which an identical compound absorbs emitted light, causing a decrease in luminescence efficiency. Since self-absorption is significantly observed in compounds with a small Stokes shift (i.e., large overlap between the absorption and fluorescence spectra), it is desirable to use compounds with a large Stokes shift (small overlap between the absorption and fluorescence spectra) to suppress self-absorption. The Stokes shift can be measured by the method described below. The compound to be measured is 2.0 × 10⁻⁶ -5 A sample for measurement is prepared by dissolving the sample in toluene at a concentration of mol / L. The sample placed in a quartz cell is irradiated with continuous light in the ultraviolet-visible region at room temperature (300 K), and the absorption spectrum (vertical axis: absorbance, horizontal axis: wavelength) is measured. A spectrophotometer can be used for measuring the absorption spectrum; for example, the Hitachi High-Tech Sciences U-3900 / 3900H spectrophotometer can be used. In addition, the compound to be measured is 4.9 × 10⁻⁶ -6 A sample for measurement is prepared by dissolving it in toluene at a concentration of mol / L. Excitation light is irradiated onto the sample placed in a quartz cell at room temperature (300 K), and the fluorescence spectrum (vertical axis: fluorescence intensity, horizontal axis: wavelength) is measured. A spectrophotometer can be used for measuring the fluorescence spectrum. For example, the F-7000 spectrofluorescence spectrophotometer from Hitachi High-Tech Science can be used. From these absorption and fluorescence spectra, the difference between the wavelength of maximum absorption and the wavelength of maximum fluorescence is calculated to obtain the Stokes shift (SS). The unit of the Stokes shift (SS) is nm.

[1646] In the organic EL device according to the present embodiment, it is preferable that the triplet energy T1 (D2) of the second luminescent compound and the triplet energy T1 (H2) of the second host material satisfy the relationship of the following formula (Equation 30A).

Furthermore, the triplet exciton generated by the recombination of holes and electrons on the second host material does not move to the second emitting compound having a higher triplet energy. The triplet exciton generated by recombination on the molecules of the second emitting compound rapidly transfers energy to the molecules of the second host material.

[1649] Triplet excitons of the second host material do not move to the second luminescent compound, and triplet excitons efficiently collide with each other on the second host material due to the TTF phenomenon, thereby generating singlet excitons.

[1652] In the organic EL device according to the present embodiment, the second luminescent compound and the second host material satisfy the relationship of the above formula (Equation 4), so that the singlet energy of the second luminescent compound is smaller than the singlet energy of the second host material, and thus the singlet exciton generated by the TTF phenomenon transfers energy from the second host material to the second luminescent compound, contributing to the fluorescent emission of the second luminescent compound.

[1653] In the organic EL device according to the present embodiment, the second luminescent compound is preferably a compound that does not contain a zygos ring structure in its molecule.

[1660] The second light-emitting layer preferably contains the second light-emitting compound in an amount of 10 mass% or less of the total mass of the second light-emitting layer, more preferably contains 7 mass% or less of the total mass of the second light-emitting layer, and even more preferably contains 5 mass% or less of the total mass of the second light-emitting layer.

[1661] The second light-emitting layer preferably contains at least 60 mass% of the total mass of the second light-emitting layer, more preferably at least 70 mass% of the total mass of the second light-emitting layer, even more preferably at least 80 mass% of the total mass of the second light-emitting layer, even more preferably at least 90 mass% of the total mass of the second light-emitting layer, and even more preferably at least 95 mass% of the total mass of the second light-emitting layer.

[1662] It is preferable that the second light-emitting layer contains the second host material in an amount of 99.5 mass% or less of the total mass of the second light-emitting layer.

[1664] In the organic EL device according to the present embodiment, the film thickness of the second light-emitting layer is preferably 5 nm or more, more preferably 10 nm or more, and even more preferably 15 nm or more. If the film thickness of the second light-emitting layer is 5 nm or more, it is easy to suppress triplet excitons that have moved from the first light-emitting layer to the second light-emitting layer from returning to the first light-emitting layer. In addition, if the film thickness of the second light-emitting layer is 5 nm or more, triplet excitons can be sufficiently separated from the recombination portion in the first light-emitting layer.
