Description

[Technical Field]

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

[0002] Organic electroluminescent elements (hereinafter sometimes referred to as "organic EL elements") are used in full-color displays such as those for mobile phones and televisions. When a voltage is applied to an organic EL element, holes are injected from the anode into the light-emitting layer, and electrons are injected from the cathode into the light-emitting layer. The injected holes and electrons then recombine in the light-emitting layer to form excitons. At this time, according to the statistical laws of electron spin, singlet excitons are generated at a rate of 25% and triplet excitons at a rate of 75%. Various studies have been conducted on compounds used in organic EL elements to improve their performance, such as luminance, emission wavelength, chromaticity, luminous efficiency, driving voltage, and lifetime. For example, Patent Document 1 describes an organic electroluminescence element that includes an anode-side light-emitting layer containing a pyrene derivative and a cathode-side light-emitting layer containing an anthracene derivative. For example, Patent Document 2 describes an organic electroluminescence device having an emitting layer containing an anthracene derivative as a host material and a pyrene derivative as a dopant material. For example, Patent Document 3 describes an organic electroluminescence element including an anode-side emitting layer containing a pyrene derivative as a host material, and a cathode-side emitting layer containing an anthracene derivative as a host material.

DETAILED DESCRIPTION OF THE INVENTION

[0017] [Definition] In this specification, hydrogen atoms include isotopes with different numbers of neutrons, namely protium, deuterium, and tritium.

[0018] In this specification, in a chemical structural formula, a hydrogen atom, i.e., a protium atom, a deuterium atom, or a tritium atom is assumed to be bonded to a possible bonding position that is not explicitly marked with a symbol such as "R" or "D" representing a deuterium atom.

[0019] As used herein, the term "number of ring carbon atoms" 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., a monocyclic compound, a fused ring compound, a bridged compound, a carbocyclic compound, and a heterocyclic compound). When the ring is substituted with a substituent, the carbon atoms contained in the substituent are not included in the number of ring carbon atoms. The "number of ring carbon atoms" described below is the same unless otherwise specified. For example, a benzene ring has 6 ring carbon atoms, a naphthalene ring has 10 ring carbon atoms, a pyridine ring has 5 ring carbon atoms, and a furan ring has 4 ring carbon atoms. For example, a 9,9-diphenylfluorenyl group has 13 ring carbon atoms, and a 9,9'-spirobifluorenyl group has 25 ring carbon atoms. Furthermore, when a benzene ring is substituted with, for example, an alkyl group as a substituent, the number of carbon atoms of the alkyl group is not included in the number of ring carbon atoms of the benzene ring. Therefore, the number of ring carbon atoms of the benzene ring substituted with an alkyl group is 6. Furthermore, when a naphthalene ring is substituted with, for example, an alkyl group as a substituent, the number of carbon atoms of the alkyl group is not included in the number of ring carbon atoms of the naphthalene ring. Therefore, the number of ring carbon atoms of the naphthalene ring substituted with an alkyl group is 10.

[0020] In this specification, the number of ring atoms refers to the number of atoms constituting the ring itself of a compound (e.g., a monocyclic compound, a fused ring compound, a bridged compound, a carbocyclic compound, and a heterocyclic compound) having a structure in which atoms are bonded in a ring (e.g., a monocyclic ring, a fused ring, and a ring assembly). Atoms that do not constitute the ring (e.g., hydrogen atoms terminating the bonds of atoms constituting the ring) and atoms contained in the substituent when the ring is substituted with a substituent are not included in the number of ring atoms. The "number of ring atoms" described below is the same unless otherwise specified. For example, the number of ring atoms of a pyridine ring is 6, the number of ring atoms of a quinazoline ring is 10, and the number of ring atoms of a furan ring is 5. For example, the number of hydrogen atoms or atoms constituting a substituent bonded to the pyridine ring are not included in the number of pyridine ring atoms. Therefore, the number of ring atoms of a pyridine ring to which a hydrogen atom or a substituent is bonded is 6. Furthermore, for example, hydrogen atoms bonded to carbon atoms of the quinazoline ring or atoms constituting substituents are not included in the number of ring atoms of the quinazoline ring, so the number of ring atoms of a quinazoline ring to which a hydrogen atom or a substituent is bonded is 10.

[0021] In this specification, the "number of carbon atoms XX to YY" in the expression "substituted or unsubstituted ZZ group having carbon atoms XX to YY" refers to the number of carbon atoms when the ZZ group is unsubstituted, and does not include the number of carbon atoms of the substituent when the ZZ group is substituted. Here, "YY" is larger than "XX", "XX" means an integer of 1 or more, and "YY" means an integer of 2 or more.

[0022] In this specification, the "number of atoms XX to YY" in the expression "a substituted or unsubstituted ZZ group having XX to YY atoms" refers to the number of atoms when the ZZ group is unsubstituted, and does not include the number of atoms of the substituent when the ZZ group is substituted. Here, "YY" is larger than "XX", "XX" means an integer of 1 or more, and "YY" means an integer of 2 or more.

[0023] In this specification, an unsubstituted ZZ group refers to a case where a "substituted or unsubstituted ZZ group" is an "unsubstituted ZZ group", and a substituted ZZ group refers to a case where a "substituted or unsubstituted ZZ group" is a "substituted ZZ group". In this specification, "unsubstituted" in the context of a "substituted or unsubstituted ZZ group" means that a hydrogen atom in the ZZ group is not replaced with a substituent. The hydrogen atom in the "unsubstituted ZZ group" is a protist atom, a deuterium atom, or a tritium atom. In this specification, "substituted" in the context of "a substituted or unsubstituted ZZ group" means that one or more hydrogen atoms in the ZZ group are replaced with a substituent. Similarly, "substituted" in the context of "a BB group substituted with an AA group" means that one or more hydrogen atoms in the BB group are replaced with an AA group.

[0102] The above is the explanation of "substituents described in this specification."

[0103] - "When bonded to form a ring" In this specification, the phrase "one or more pairs of adjacent groups bond with each other to form a substituted or unsubstituted monocycle, bond with each other to form a substituted or unsubstituted fused ring, or are not bonded to each other" means the case where "one or more pairs of adjacent groups bond with each other to form a substituted or unsubstituted monocycle", the case where "one or more pairs of adjacent groups bond with each other to form a substituted or unsubstituted fused ring", or the case where "one or more pairs of adjacent groups do not bond with each other". In this specification, the cases where "one or more groups of two or more adjacent groups bond to each other to form a substituted or unsubstituted monocyclic ring" and "one or more groups of two or more adjacent groups bond to each other to form a substituted or unsubstituted fused ring" (hereinafter, these cases may be collectively referred to as "a case where they bond to form a ring") will be explained below. The case of an anthracene compound represented by the following general formula (TEMP-103), in which the main skeleton is an anthracene ring, will be explained as an example.

[0104] [ka]

[0105] For example, R921 ~R 930 In the case where "one or more pairs of adjacent two or more groups are bonded to each other to form a ring," one pair of adjacent two groups is R 921 and R 922 Paired with R 922 and R 923 Paired with R 923 and R 924 Paired with R 924 and R 930 Paired with R 930 and R 925 Paired with R 925 and R 926 Paired with R 926 and R 927 Paired with R 927 and R 928 Paired with R 928 and R 929 Pairs with and R 929 and R 921 It is paired with.

[0106] The above "one or more pairs" means that two or more pairs of adjacent two or more groups may simultaneously form a ring. For example, R 921 and R 922 and are bonded to each other to form ring Q A At the same time, R 925 and R 926 and are bonded to each other to form ring Q B When the anthracene compound represented by the general formula (TEMP-103) is formed, the anthracene compound represented by the general formula (TEMP-104) is represented by the following general formula (TEMP-104).

[0107] [ka]

[0108] When a "set of two or more adjacent units" forms a ring, it does not only mean that a set of two adjacent units is bonded, as in the previous example, but also that a set of three or more adjacent units is bonded. For example, R 921 and R 922 and are bonded to each other to form ring Q A and R 922 and R923 and are bonded to each other to form ring Q C and form three adjacent (R 921 , R 922 and R 923 In this case, the anthracene compound represented by the general formula (TEMP-103) is represented by the following general formula (TEMP-105): A and Ring Q C is R 922 Share.

[0109] [ka]

[0110] The "monocyclic ring" or "fused ring" formed may be a saturated ring or an unsaturated ring as the structure of only the ring formed. Even when "one pair of adjacent two" forms a "monocyclic ring" or a "fused ring", the "monocyclic ring" or the "fused ring" may form a saturated ring or an unsaturated ring. For example, in the case of the ring Q formed in the general formula (TEMP-104), A and Ring Q B are "monocyclic rings" or "fused rings", respectively. A , and ring Q C is a "fused ring". A and Tamaki Q C That is, Tamaki Q A and Tamaki Q C The ring Q in the general formula (TMEP-104) is fused to form a fused ring. A If is a benzene ring, then ring Q A The ring Q in the general formula (TMEP-104) is a monocyclic ring. A If is a naphthalene ring, then ring Q A is a fused ring.

[0111] The term "unsaturated ring" refers to an aromatic hydrocarbon ring or an aromatic heterocyclic ring. The term "saturated ring" refers to an aliphatic hydrocarbon ring or a non-aromatic heterocyclic ring. Specific examples of the aromatic hydrocarbon ring include structures in which the groups given as specific examples in the specific example group G1 are terminated with a hydrogen atom. Specific examples of the aromatic heterocycle include structures in which the aromatic heterocyclic groups exemplified as specific examples in the specific example group G2 are terminated with a hydrogen atom. Specific examples of the aliphatic hydrocarbon ring include structures in which the groups given as specific examples in the specific example group G6 are terminated with a hydrogen atom. The term "forming a ring" means that a ring is formed only with a plurality of atoms of the main skeleton, or with a plurality of atoms of the main skeleton and one or more optional elements. For example, R 921 and R 922 and Q are bonded together to form a ring A is R 921 The carbon atom of the anthracene skeleton to which R is bonded 922 It means a ring formed by the carbon atom of the anthracene skeleton to which R is bonded and one or more arbitrary elements. 921 and R 922 Todekan Q A In the case where R 921 The carbon atom of the anthracene skeleton to which R is bonded 922 When a monocyclic unsaturated ring is formed with the carbon atom of the anthracene skeleton to which R is bonded and four carbon atoms, 921 and R 922 The ring formed by

[0112] Here, unless otherwise specified in this specification, the "arbitrary element" is preferably at least one element selected from the group consisting of carbon, nitrogen, oxygen, and sulfur. In the arbitrary element (for example, in the case of carbon or nitrogen), the bond that does not form a ring may be terminated with a hydrogen atom or the like, or may be substituted with an "arbitrary substituent" described below. When an arbitrary element other than carbon is included, the formed ring is a heterocycle. Unless otherwise specified in this specification, the "one or more arbitrary elements" constituting the monocyclic or fused ring is preferably 2 or more and 15 or less, more preferably 3 or more and 12 or less, and even more preferably 3 or more and 5 or less. Unless otherwise specified in this specification, of the "monocyclic ring" and the "fused ring", the "monocyclic ring" is preferred. Unless otherwise specified in this specification, of the "saturated ring" and the "unsaturated ring", the "unsaturated ring" is preferred. Unless otherwise specified herein, a "monocyclic ring" is preferably a benzene ring. Unless otherwise specified herein, the "unsaturated ring" is preferably a benzene ring. When "one or more pairs of adjacent two or more groups" "combine with each other to form a substituted or unsubstituted monocyclic ring" or "combine with each other to form a substituted or unsubstituted fused ring," unless otherwise specified in this specification, preferably, one or more pairs of adjacent two or more groups combine with each other to form a substituted or unsubstituted "unsaturated ring" consisting of a plurality of atoms of the parent skeleton and at least one element selected from the group consisting of 1 to 15 carbon atoms, nitrogen atoms, oxygen atoms, and sulfur atoms.

[0113] When the above-mentioned "monocyclic ring" or "fused ring" has a substituent, the substituent is, for example, the "optional substituent" described later. When the above-mentioned "monocyclic ring" or "fused ring" has a substituent, specific examples of the substituent are the substituents described in the above section "Substituents described in this specification." When the above-mentioned "saturated ring" or "unsaturated ring" has a substituent, the substituent is, for example, the "optional substituent" described below.

[0651] In the organic EL device according to this embodiment, the seventh compound is preferably a compound that emits light with a main peak wavelength of 430 nm or more and 480 nm or less.

[0652] The method for measuring the maximum peak wavelength of a compound is as follows. -6 mol / L or more 10 -5 A toluene solution of 1000 mol / L or less is prepared and placed in a quartz cell, and the emission spectrum (vertical axis: emission intensity, horizontal axis: wavelength) of this sample is measured at room temperature (300 K). The emission spectrum can be measured using a spectrophotometer (device name: F-7000) manufactured by Hitachi High-Tech Science Corporation. Note that the emission spectrum measurement device is not limited to the device used here. In the emission spectrum, the peak wavelength at which the emission intensity is maximum is defined as the maximum emission peak wavelength. Note that in this specification, the maximum peak wavelength of fluorescent emission may also be referred to as the maximum fluorescent emission peak wavelength (FL-peak).

Conversion formula (F2): S1[eV]=1239.85 / λedge An example of an absorption spectrum measuring device is a spectrophotometer (device name: U3310) manufactured by Hitachi, Ltd., but is not limited to this.

[0656] The tangent to the fall on the long wavelength side of the absorption spectrum is drawn as follows. When moving along the spectral curve from the longest maximum value on the longest wavelength side of the absorption spectrum toward longer wavelengths, consider the tangent at each point on the curve. As the curve falls (i.e., as the value on the vertical axis decreases), the slope of this tangent decreases and then increases repeatedly. The tangent drawn at the point where the slope is minimum on the longest wavelength side (excluding cases where the absorbance is 0.1 or less) is considered to be the tangent to the fall on the long wavelength side of the absorption spectrum. Note that maximum points with absorbance values ​​of 0.2 or less are not included in the maximum values ​​on the longest wavelength side.

[0739] The structure of the organic EL element according to this embodiment will be further described below.

[0740] (substrate) The substrate is used as a support for the organic EL element. Examples of materials that can be used for the substrate include glass, quartz, and plastic. A flexible substrate may also be used. A flexible substrate is a substrate that can be bent (flexible), and examples thereof include a plastic substrate. Examples of materials for forming the plastic substrate include polycarbonate, polyarylate, polyethersulfone, polypropylene, polyester, polyvinyl fluoride, polyvinyl chloride, polyimide, and polyethylene naphthalate. Inorganic vapor-deposited films may also be used.

[0741] (anode) The anode formed on the substrate is preferably made of a metal, alloy, electrically conductive compound, or mixture thereof with a large work function (specifically, 4.0 eV or higher). Specific examples include indium tin oxide (ITO), indium tin oxide containing silicon or silicon oxide, indium zinc oxide, tungsten oxide, indium oxide containing zinc oxide, and graphene. Other examples include gold (Au), platinum (Pt), nickel (Ni), tungsten (W), chromium (Cr), molybdenum (Mo), iron (Fe), cobalt (Co), copper (Cu), palladium (Pd), titanium (Ti), or nitrides of metal materials (e.g., titanium nitride).

[0742] These materials are usually formed into films by sputtering. For example, indium oxide-zinc oxide can be formed by sputtering using a target containing 1% by mass or more and 10% by mass or less of zinc oxide added to indium oxide. Furthermore, for example, indium oxide containing tungsten oxide and zinc oxide can be formed by sputtering using a target containing 0.5% by mass or more and 5% by mass or less of tungsten oxide and 0.1% by mass or more and 1% by mass or less of zinc oxide relative to indium oxide.

Vacuum deposition and sputtering methods can be used to form the anode using alkali metals, alkaline earth metals, and alloys containing these metals. Furthermore, when using silver paste, coating methods and inkjet methods can be used.

[0747] By providing an electron injection layer, the cathode can be formed using various conductive materials, regardless of the magnitude of the work function, such as Al, Ag, ITO, graphene, indium oxide-tin oxide containing silicon or silicon oxide, etc. These conductive materials can be deposited by sputtering, inkjet printing, spin coating, etc.

[0750] Furthermore, polymeric compounds (oligomers, dendrimers, polymers, etc.) can also be used as materials with high hole injection properties. Examples include poly(N-vinylcarbazole) (abbreviation: PVK), poly(4-vinyltriphenylamine) (abbreviation: PVTPA), poly[N-(4-{N'-[4-(4-diphenylamino)phenyl]phenyl-N'-phenylamino}phenyl)methacrylamide] (abbreviation: PTPDMA), and poly[N,N'-bis(4-butylphenyl)-N,N'-bis(phenyl)benzidine] (abbreviation: Poly-TPD).

[0763] (electron injection layer) The electron injection layer is a layer containing a substance with high electron injection properties. For the electron injection layer, alkali metals, alkaline earth metals, such as lithium (Li), cesium (Cs), calcium (Ca), lithium fluoride (LiF), cesium fluoride (CsF), calcium fluoride (CaF), and lithium oxide (LiOx), or compounds thereof can be used. Alternatively, a substance having electron transport properties containing an alkali metal, alkaline earth metal, or a compound thereof, such as Alq containing magnesium (Mg), can be used. In this case, electron injection from the cathode can be performed more efficiently.

[0764] Alternatively, the electron injection layer may be formed using a composite material obtained by mixing an organic compound and an electron donor (donor). Such composite materials have excellent electron injection and electron transport properties because electrons are generated in the organic compound by the electron donor.

[0767] (Layer formation method) The method for forming each layer of the organic EL element of this embodiment is not limited to those specifically mentioned above, but known methods can be used, such as dry film formation methods such as vacuum deposition, sputtering, plasma deposition, and ion plating, and wet film formation methods such as spin coating, dipping, flow coating, and inkjet deposition.

[0768] (film thickness) The thickness of each organic layer in the organic EL device of this embodiment is not limited unless otherwise specified above. Generally, if the thickness is too thin, defects such as pinholes are likely to occur, and if the thickness is too thick, a high applied voltage is required, resulting in poor efficiency. Therefore, the thickness of each organic layer in the organic EL device is usually preferably in the range of several nm to 1 μm.

[0769] (Emission wavelength of organic EL element) The organic electroluminescent element according to this embodiment preferably emits light having a maximum peak wavelength of 430 nm or more and 480 nm or less when the element is driven. The maximum peak wavelength of light emitted from the organic EL element when the element is driven is measured as follows: 2A voltage is applied to the organic EL element so that the spectral radiance spectrum is measured using a spectroradiometer CS-2000 (Konica Minolta, Inc.) In the obtained spectral radiance spectrum, the peak wavelength of the emission spectrum at which the emission intensity is maximum is measured and this is defined as the maximum peak wavelength (unit: nm).

[0770] According to this embodiment, it is possible to provide an organic electroluminescence element that emits light with high luminous efficiency and a long life.

[0771] Second Embodiment (organic electroluminescence element) The structure of the organic EL element according to the second embodiment will be described. The organic EL element according to the second embodiment differs from the organic EL element according to the first embodiment in terms of the first light-emitting layer and the second light-emitting layer, but is otherwise similar to the organic EL element according to the first embodiment. Therefore, in the description of the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals or names, and the description thereof will be omitted or simplified. Furthermore, in the second embodiment, the same element configurations, materials, and compounds as those described in the first embodiment can be used for element configurations, materials, and compounds that are not specifically mentioned.

[0772] The organic EL device according to this embodiment includes an anode, a cathode, a first light-emitting layer and a second light-emitting layer disposed between the anode and the cathode and in direct contact with each other, and a first electron transport layer disposed between the first light-emitting layer and the second light-emitting layer in direct contact with each other and the cathode, wherein the first light-emitting layer contains a first compound as a first host material, and the second light-emitting layer contains a second compound as a second host material, the first host material and the second host material being different from each other, and the first light-emitting layer emits light having a maximum peak wavelength of 500 nm or less. the second emitting layer contains at least a compound that exhibits emission with a maximum peak wavelength of 500 nm or less, the compound contained in the first emitting layer and the compound contained in the second emitting layer that exhibits emission with a maximum peak wavelength of 500 nm or less are the same as or different from each other, 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 mathematical formula (Mathematical Formula 1A), and the first electron-transporting layer contains a third compound. T1(H1)>T1(H2) ...(Math 1A)

[0773] The third compound contained in the first electron transport layer of the organic EL device according to this embodiment is the same compound as the third compound described in the first embodiment.

[0774] Triplet-Triplet-Annhilation (sometimes referred to as TTA) has been known as a technique for improving the luminous efficiency of organic electroluminescence devices. TTA is a mechanism in which triplet excitons collide with other triplet excitons to generate singlet excitons. The TTA mechanism is also sometimes referred to as the TTF mechanism. TTF is an abbreviation for Triplet-Triplet Fusion.

[0775] The TTF phenomenon will be explained. Holes injected from the anode and electrons injected from the cathode recombine in the light-emitting layer to generate excitons. As has been conventionally known, the spin state of these excitons is 25% singlet excitons and 75% triplet excitons. In conventional fluorescent elements, 25% of the singlet excitons emit light when they relax to the ground state, but the remaining 75% of the triplet excitons return to the ground state through a thermal deactivation process without emitting light. Therefore, the theoretical limit of the internal quantum efficiency of conventional fluorescent elements was said to be 25%. On the other hand, the behavior of triplet excitons generated inside organic materials has been theoretically investigated. According to S.M. Bachilo et al. (J.Phys.Chem.A,104,7711(2000)), assuming that higher-order excitons such as quintets immediately return to triplets, triplet excitons (hereinafter referred to as triplet excitons) 3 A * When the density of triplet excitons (hereinafter referred to as triplet excitons) increases, triplet excitons collide with each other, causing the reaction shown in the following formula: 1 A represents the ground state, 1 A * represents the lowest excited singlet exciton. 3 A * + 3 A * →(4 / 9) 1 A+(1 / 9) 1 A * +(13 / 9) 3 A * That is, 5 3 A * →4 1 A+1A *It is predicted that 1 / 5, or 20%, of the 75% of triplet excitons initially generated will convert to singlet excitons. Therefore, the singlet excitons contributing to light are 40%, calculated by adding 75% × (1 / 5) = 15% to the initially generated 25%. In this case, the TTF ratio (TTF ratio) of the total luminescence intensity is 15 / 40, or 37.5%. Furthermore, if we assume that singlet excitons are generated by collisions between the initially generated 75% triplet excitons (i.e., one singlet exciton is generated from two triplet excitons), then an extremely high internal quantum efficiency of 62.5% is obtained by adding 75% × (1 / 2) = 37.5% to the initially generated 25% singlet excitons. In this case, the TTF ratio is 37.5 / 62.5 = 60%.

[0776] According to the organic electroluminescent device of this embodiment, triplet excitons generated by recombination of holes and electrons in the first light-emitting layer are thought to be less likely to be quenched at the interface between the first light-emitting layer and the organic layer, even if excess carriers are present 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, when the recombination region is locally present at the interface between the first light-emitting layer and the hole transport layer or the electron blocking layer, quenching by excess electrons is thought to be possible. On the other hand, when the recombination region is locally present at the interface between the first light-emitting layer and the electron transport layer or the hole blocking layer, quenching by excess holes is thought to be possible. The organic electroluminescent device according to this embodiment includes at least two light-emitting layers (i.e., a first light-emitting layer and a second light-emitting layer) that satisfy a predetermined relationship, 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 mathematical formula (Mathematical Formula 1A). By providing the first and second light-emitting layers so as to satisfy the relationship of the above mathematical formula (Mathematical Formula 1A), triplet excitons generated in the first light-emitting layer can migrate to the second light-emitting layer without being quenched by excess carriers, and reverse migration from the second light-emitting layer to the first light-emitting layer can be suppressed. As a result, the TTF mechanism is exerted in the second light-emitting layer, singlet excitons are efficiently generated, and luminous efficiency is improved. In this way, the organic electroluminescent device has a first light-emitting layer that mainly generates triplet excitons and a second light-emitting layer that mainly exhibits the TTF mechanism by utilizing triplet excitons transferred from the first light-emitting layer, as distinct regions. By using a compound having a smaller triplet energy than the first host material in the first light-emitting layer as the second host material in the second light-emitting layer, and by creating a difference in triplet energy, the luminous efficiency is improved.

[0777] In the organic EL device according to this 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 mathematical formula (Mathematical Formula 5).

The method for measuring the maximum peak wavelength of the compound is as described above.

[0787] In the emission spectrum of the first dopant material, when the peak at which the emission intensity is greatest is defined as the maximum peak and the height of the maximum peak is defined as 1, the heights of other peaks appearing in the emission spectrum are preferably less than 0.6. Note that the peaks in the emission spectrum are defined as local maxima. In addition, it is preferable that the number of peaks in the emission spectrum of the first dopant material is less than three.

[0788] In the organic EL device according to this embodiment, the first light-emitting layer preferably emits light having a maximum peak wavelength of 500 nm or less when the device is in operation. The maximum peak wavelength of the light emitted from the light-emitting layer when the device is operating can be measured by the following method.

[0789] The maximum peak wavelength λp of the light emitted from the light-emitting layer when the device is operating The maximum peak wavelength λp1 of the light emitted from the first light-emitting layer when the device is driven is determined by the following equation: 2 The spectral radiance spectrum when a voltage is applied to the element so that the spectral radiance spectrum is measured using a spectroradiometer CS-2000 (manufactured by Konica Minolta, Inc.) The maximum peak wavelength λp1 (unit: nm) is calculated from the obtained spectral radiance spectrum. The maximum peak wavelength λp2 of the light emitted from the second light-emitting layer when the device is driven is determined by the following equation: 2The spectral radiance spectrum when a voltage is applied to the element so that the spectral radiance spectrum is measured using a spectroradiometer CS-2000 (manufactured by Konica Minolta, Inc.)

S1(H1)>S1(D1) ... (Number 20) The singlet energy S1 means the energy difference between the lowest excited singlet state and the ground state.

[0791] When the first host material and the first dopant material satisfy the relationship of the above-mentioned mathematical formula (Mathematical Formula 20), singlet excitons generated on the first host material can easily transfer energy from the first host material to the first dopant material, contributing to the fluorescent emission of the first dopant material.

T1(D1)>T1(H1) ... (Mathematics 2A)

[0793] When the first host material and the first dopant material satisfy the relationship of the above mathematical formula (Mathematical Formula 2A), triplet excitons generated in the first emitting layer move on the first host material rather than on the first dopant material having a higher triplet energy, and therefore are more likely to move to the second emitting layer.

[0794] The organic EL element according to this embodiment preferably satisfies the relationship of the following mathematical formula (Mathematical Formula 2B). T1(D1)>T1(H1)>T1(H2) ... (Math 2B)

[0795] (Triplet energy T1) The triplet energy T1 can be measured by the following method. The compound to be measured was dissolved in EPA (diethyl ether: isopentane: ethanol = 5:5:2 (volume ratio)) at 10 -5 mol / L or more 10 -4 The phosphorescence spectrum (vertical axis: phosphorescence intensity, horizontal axis: wavelength) of this sample is measured at low temperature (77[K]), and a tangent line is drawn to the rising edge of the short wavelength side of this phosphorescence spectrum. The wavelength value λ at the intersection of this tangent line and the horizontal axis is determined. edge Based on [nm], the amount of energy calculated using the following conversion formula (F1) is taken as the triplet energy T1. Conversion formula (F1): T1[eV]=1239.85 / λ edge

[0796] The tangent to the rising edge of the phosphorescence spectrum on the short wavelength side is drawn as follows: When moving along the spectral curve from the short wavelength side of the phosphorescence spectrum to the shortest maximum of the spectral maxima, consider the tangent at each point on the curve toward the long wavelength side. The slope of this tangent increases as the curve rises (i.e., as the vertical axis increases). The tangent drawn at the point where this slope is at its maximum (i.e., the tangent at the inflection point) is the tangent to the rising edge of the phosphorescence spectrum on the short wavelength side. Note that a maximum point having a peak intensity that is 15% or less of the maximum peak intensity of the spectrum is not included in the above-mentioned maximum value on the shortest wavelength side, and the tangent drawn at the point where the slope value is the maximum value that is closest to the maximum value on the shortest wavelength side is defined as the tangent to the rising edge on the short wavelength side of the phosphorescence spectrum. Phosphorescence can be measured using an F-4500 spectrofluorophotometer manufactured by Hitachi High-Technologies Corp. However, the measuring device is not limited to this, and measurements may also be performed by combining a cooling device, a cryogenic container, an excitation light source, and a light-receiving device.

[0797] In the organic EL device according to this embodiment, it is also preferable that the electron mobility μH1 of the first host material and the electron mobility μH2 of the second host material satisfy the relationship of the following mathematical formula (Mathematical Formula 6). μH2>μH1…(Equation 6)

[0798] When the first host material and the second host material satisfy the relationship of the above mathematical formula (Mathematical Formula 6), the recombination ability of holes and electrons in the first light-emitting layer is improved.

[0799] The electron mobility can be measured using impedance spectroscopy as follows. A measurement target layer with a thickness of 100 nm to 200 nm is sandwiched between an anode and a cathode, and a small AC voltage of 100 mV or less is applied while a bias DC voltage is applied. The AC current value (absolute value and phase) that flows during this process is measured. This measurement is performed while changing the frequency of the AC voltage, and complex impedance (Z) is calculated from the current and voltage values. The frequency dependence of the imaginary part (ImM) of the modulus M = iωZ (i: imaginary unit, ω: angular frequency) is calculated, and the reciprocal of the frequency ω at which ImM reaches its maximum value is defined as the response time of electrons conducting within the measurement target layer. Electron mobility is then calculated using the following formula: Electron mobility = (film thickness of the layer to be measured) 2 / (response time·voltage)

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

[0801] In the organic EL device according to this embodiment, the first emitting layer preferably contains the first compound as a first host material in an amount of 60 mass % or more of the total mass of the first emitting layer, more preferably 70 mass % or more of the total mass of the first emitting layer, even more preferably 80 mass % or more of the total mass of the first emitting layer, still more preferably 90 mass % or more of the total mass of the first emitting layer, and even more preferably 95 mass % or more of the total mass of the first emitting layer. The first emitting layer preferably contains the first host material in an amount of 99% by mass or less of the total mass of the first emitting layer. However, when the first emitting layer contains a first host material and a first dopant material, the upper limit of the total content of the first host material and the first dopant material is 100% by mass.

[0802] In this embodiment, the first emitting layer may contain materials other than the first host material and the first dopant material. The first light-emitting layer may contain only one type of first host material or two or more types of first dopant materials.

[0803] In the organic EL device according to this embodiment, the thickness of the first light-emitting layer is preferably 3 nm or more, more preferably 5 nm or more, which is sufficient to cause recombination of holes and electrons in the first light-emitting layer. In the organic EL device according to this embodiment, the thickness of the first emitting layer is preferably 15 nm or less, more preferably 10 nm or less, which is thin enough to allow triplet excitons to migrate to the second emitting layer.

[0804] (Second light-emitting layer) The second light-emitting layer contains a second host material, which is a compound different from the first host material contained in the first light-emitting layer. The second emitting layer contains at least a compound that exhibits fluorescent emission with a maximum peak wavelength of 500 nm or less. This "compound that exhibits fluorescent emission with a maximum peak wavelength of 500 nm or less" may be the second host material or a compound different from the second host material. The compound contained in the second emitting layer that exhibits fluorescent emission with a maximum peak wavelength of 500 nm or less is preferably a compound that exhibits fluorescent emission with a maximum peak wavelength of 500 nm or less. The method for measuring the maximum peak wavelength of the compound is as described above.

[0805] In the organic EL device according to this embodiment, the second light-emitting layer further contains a second dopant material, and the second dopant material is preferably a fluorescent compound.

[0806] In the organic EL device according to this embodiment, the second dopant material is preferably a compound that exhibits luminescence with a maximum peak wavelength of 500 nm or less, and more preferably a compound that exhibits fluorescent luminescence with a maximum peak wavelength of 500 nm or less.

[0807] In the organic EL device according to this embodiment, the second light-emitting layer preferably emits light having a maximum peak wavelength of 500 nm or less when the device is in operation.

[0808] In the organic EL device according to this embodiment, the half width of the maximum peak of the second dopant material is preferably 1 nm or more and 20 nm or less.

[0809] In the organic EL device according to this embodiment, the Stokes shift of the second dopant material preferably exceeds 7 nm. If the Stokes shift of the second dopant material exceeds 7 nm, it becomes easier to prevent a decrease in luminous efficiency due to self-absorption. Self-absorption is a phenomenon in which emitted light is absorbed by the same compound, resulting in a decrease in luminous efficiency. Self-absorption is most pronounced in compounds with a small Stokes shift (i.e., a large overlap between the absorption spectrum and the fluorescence spectrum). Therefore, to suppress self-absorption, it is preferable to use a compound with a large Stokes shift (a small overlap between the absorption spectrum and the fluorescence spectrum). The Stokes shift can be measured by the method described in the Examples.

T1(D2)>T1(H2) ... (Number 3)

[0811] In the organic EL device according to this embodiment, the second dopant material and the second host material satisfy the relationship of the above mathematical formula (Mathematical Formula 3), and therefore, when triplet excitons generated in the first emitting layer move to the second emitting layer, they transfer their energy to molecules of the second host material, not to molecules of the second dopant material having a higher triplet energy. Furthermore, triplet excitons generated by recombination of holes and electrons on the second host material do not transfer to molecules of the second dopant material having a higher triplet energy. Triplet excitons generated by recombination on molecules of the second dopant material quickly transfer their energy to molecules of the second host material. Triplet excitons in the second host material do not transfer to the second dopant material, but instead collide efficiently with each other on the second host material due to the TTF phenomenon, generating singlet excitons.

[0812] In the organic EL device according to this embodiment, it is preferable that the singlet energy S1(H2) of the second host material and the singlet energy S1(D2) of the second dopant material satisfy the relationship of the following mathematical formula (Mathematical Formula 4). S1(H2)>S1(D2)…(Number 4)

[0813] In the organic EL device according to this embodiment, the second dopant material and the second host material satisfy the relationship of the above-mentioned mathematical formula (Mathematical Formula 4), and therefore the singlet energy of the second dopant material is smaller than the singlet energy of the second host material. Therefore, the singlet excitons generated by the TTF phenomenon transfer energy from the second host material to the second dopant material, contributing to the fluorescent emission of the second dopant material.

[0814] In the organic EL device according to this embodiment, the second dopant material is preferably a compound that does not contain an azine ring structure in the molecule.

[0815] In the organic EL device according to this embodiment, the second dopant material is preferably not a boron-containing complex, and more preferably not a complex.

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

[0819] The second emitting layer preferably contains the second compound as a second host material in an amount of 60 mass% or more of the total mass of the second emitting layer, more preferably 70 mass% or more of the total mass of the second emitting layer, even more preferably 80 mass% or more of the total mass of the second emitting layer, still more preferably 90 mass% or more of the total mass of the second emitting layer, and even more preferably 95 mass% or more of the total mass of the second emitting layer. The second emitting layer preferably contains the second host material in an amount of 99% by mass or less of the total mass of the second emitting layer. When the second emitting layer contains a second host material and a second dopant material, the upper limit of the total content of the second host material and the second dopant material is 100% by mass.

[0820] Note that this embodiment does not exclude the case where the second emitting layer contains a material other than the second host material and the second dopant material. The second light-emitting layer may contain only one type of second host material or two or more types of second dopant materials.

[0821] In the organic EL device according to this embodiment, the thickness of the second emitting layer is preferably 5 nm or more, more preferably 15 nm or more. When the thickness of the second emitting layer is 5 nm or more, triplet excitons that have migrated from the first emitting layer to the second emitting layer can be easily prevented from returning to the first emitting layer. Furthermore, when the thickness of the second emitting layer is 5 nm or more, triplet excitons can be sufficiently separated from the recombination site in the first emitting layer. In the organic EL device according to this embodiment, the thickness of the second light-emitting layer is preferably 20 nm or less, which can increase the density of triplet excitons in the second light-emitting layer and make the TTF phenomenon more likely to occur. In the organic EL device according to this embodiment, the second light-emitting layer preferably has a thickness of 5 nm or more and 20 nm or less.
