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%. In order to improve the performance of organic EL elements, various studies have been conducted on compounds used in organic EL elements (see, for example, Patent Documents 1 to 6). Examples of the performance of organic EL elements include brightness, emission wavelength, chromaticity, luminous efficiency, driving voltage, and lifespan. [Prior art documents] [Patent documents]

[0033] [Definition] In this specification, hydrogen atoms include isotopes with different numbers of neutrons, namely protium, deuterium, and tritium.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0118] The above is the explanation of "substituents described in this specification."

[0119] - "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.

[0120] [ka]

[0121] 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," the 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.

[0122] 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).

[0123] [ka]

[0124] 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.

[0125] [ka]

[0126] 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.

[0127] 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 are bonded to form a ring Q 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

[0128] 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.

[0129] 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. 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." The above is an explanation of the case where "one or more pairs of adjacent groups bond to each other to form a substituted or unsubstituted monocyclic ring" and the case where "one or more pairs of adjacent groups bond to each other to form a substituted or unsubstituted fused ring" ("when bonded to form a ring").

[0305] The second compound represented by the general formula (2-1B) does not include a compound represented by the following general formula (200B). The compound represented by the following general formula (200B) has a relatively high crystallinity, which poses a problem in terms of mass production. This is because highly crystalline materials are prone to crucible clogging. Crucible clogging refers to the following phenomenon. When a light-emitting layer is formed by vapor deposition using a crucible containing a compound to be formed into a film, the sublimated material may adhere to the opening of the crucible, blocking it. If the opening of the crucible becomes narrow, the compound to be formed into a film is less likely to escape from the crucible, making it impossible to form the compound into a desired film thickness on a substrate or the like. Patent Document 6 discloses an example of forming a light-emitting layer using a compound represented by the following general formula (200B) (compound (1-134-0)). However, the compound represented by the following general formula (200B) has a relatively high crystallinity, and therefore may cause clogging of the crucible during film formation. The problem with Patent Document 6 is thought to be improving the crystallinity of compound (1-134-0).

[0740] The main peak wavelength of a compound is measured 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 main emission peak wavelength. In this specification, the main peak wavelength may also be referred to as the main fluorescence emission peak wavelength (FL-peak).

[0741] In the organic EL device according to this embodiment, when the first light-emitting layer contains a first compound and a third compound, the first compound is preferably a host material (sometimes referred to as a matrix material), and the third compound is preferably a dopant material (sometimes referred to as a guest material, an emitter, or a light-emitting material).

[0742] In the organic EL device according to this embodiment, when the first light-emitting layer contains the first compound and the third compound, it is preferable that the singlet energy S1(H1) of the first compound and the singlet energy S1(D3) of the third compound satisfy the relationship shown in the following formula (Mathematical Formula 1).

[0745] (singlet energy S1) The following method can be mentioned as a method for measuring the singlet energy S1 using a solution (sometimes referred to as a solution method). 10 of the compounds to be measured -5 mol / L or more 10 -4A toluene solution of 1000 mol / L or less is prepared and placed in a quartz cell, and the absorption spectrum (vertical axis: absorption intensity, horizontal axis: wavelength) of this sample is measured at room temperature (300 K). A tangent line is drawn to the falling edge on the long wavelength side of this absorption spectrum, and the wavelength value λedge [nm] at the intersection of this tangent line and the horizontal axis is substituted into the following conversion formula (F2) to calculate the singlet energy. Conversion formula (F2): S1[eV]=1239.85 / λedge An example of an absorption spectrum measuring device is a spectrophotometer manufactured by Hitachi (device name: U3310), but is not limited to this.

[0746] 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.

[0748] When the first compound and the second compound satisfy the relationship of the above mathematical formula (Mathematical formula 3), the recombination ability of holes and electrons in the first light-emitting layer is improved.

[0749] 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)

Furthermore, the first and second light-emitting layers preferably do not contain heavy metal complexes or phosphorescent rare earth metal complexes, such as iridium complexes, osmium complexes, and platinum complexes.

Polymer compounds such as poly(N-vinylcarbazole) (abbreviated as PVK) and poly(4-vinyltriphenylamine) (abbreviated as PVTPA) may also be used.

[0770] However, other substances may be used as long as they have a higher hole-transporting property than an electron-transporting property.

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.

[0774] 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. In this case, the organic compound is preferably a material that is excellent at transporting the generated electrons. Specifically, for example, the above-mentioned substances constituting the electron transport layer (metal complexes, heteroaromatic compounds, etc.) can be used. The electron donor may be any substance that exhibits electron donating properties to the organic compound.

[0775] (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.

[0776] (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.

[0777] According to this embodiment, it is possible to provide an organic electroluminescence element with improved luminous efficiency. In the organic EL device according to this embodiment, a first emitting layer containing a first compound represented by the general formula (1) or the like as a first host material is in direct contact with a second emitting layer containing a second compound represented by the general formula (2) or the like as a second host material. By stacking the first emitting layer and the second emitting layer in this manner, the generated singlet excitons and triplet excitons can be effectively utilized, and as a result, the luminous efficiency of the organic EL device can be improved.

[0778] Second Embodiment (electronic equipment) The electronic device according to this embodiment is equipped with the organic EL element according to any one of the above-described embodiments. Examples of the electronic device include a display device and a light-emitting device. Examples of the display device include display components (e.g., an organic EL panel module), a television, a mobile phone, a tablet, and a personal computer. Examples of the light-emitting device include lighting and vehicle lighting fixtures.

[0779] [Modifications of the embodiment] The present invention is not limited to the above-described embodiment, and any modifications and improvements that can achieve the object of the present invention are included in the present invention.

[0780] For example, the number of light-emitting layers is not limited to two, and more than two light-emitting layers may be stacked. When the organic EL element has more than two light-emitting layers, it is sufficient that at least two of the light-emitting layers satisfy the conditions described in the above embodiment. For example, the other light-emitting layer may be a fluorescent light-emitting layer or a phosphorescent light-emitting layer that utilizes light emission by electron transition from a triplet excited state directly to the ground state. Furthermore, when the organic EL element has a plurality of light-emitting layers, these light-emitting layers may be provided adjacent to each other, or the organic EL element may be a so-called tandem type organic EL element in which a plurality of light-emitting units are stacked via an intermediate layer.

[0781] Furthermore, for example, a blocking layer may be provided adjacent to at least one of the anode side and the cathode side of the light-emitting layer. The blocking layer is preferably disposed in contact with the light-emitting layer and blocks at least one of holes, electrons, and excitons. For example, when a blocking layer is disposed adjacent to the cathode side of the light-emitting layer, the blocking layer transports electrons and prevents holes from reaching a layer (e.g., an electron transport layer) located closer to the cathode than the blocking layer. When the organic EL device includes an electron transport layer, it is preferable to include the blocking layer between the light-emitting layer and the electron transport layer. Furthermore, when a blocking layer is disposed in contact with the light-emitting layer on the anode side, the blocking layer transports holes and prevents electrons from reaching a layer (e.g., a hole transport layer) located closer to the anode than the blocking layer. When the organic EL device includes a hole transport layer, it is preferable to include the blocking layer between the light-emitting layer and the hole transport layer. A barrier layer may be provided adjacent to the light-emitting layer to prevent excitation energy from leaking from the light-emitting layer to surrounding layers, and prevents excitons generated in the light-emitting layer from migrating to layers closer to the electrode than the barrier layer (e.g., electron transport layer and hole transport layer). The light-emitting layer and the barrier layer are preferably in contact with each other.

[0782] In addition, the specific structure and shape in carrying out the present invention may be other structures within the scope of achieving the object of the present invention. [Example]

[0857] <Fabrication of organic EL element 1> An organic EL device was fabricated and evaluated as follows.

[0858] [Reference example 1] A 25mm x 75mm x 1.1mm thick glass substrate (manufactured by Geomatec Co., Ltd.) with an ITO (Indium Tin Oxide) transparent electrode (anode) was ultrasonically cleaned in isopropyl alcohol for 5 minutes, followed by UV ozone cleaning for 30 minutes. The ITO transparent electrode had a film thickness of 130nm. The cleaned glass substrate with transparent electrode lines was attached to a substrate holder in a vacuum deposition apparatus, and compound HA1 was first deposited on the surface on which the transparent electrode lines were formed so as to cover the transparent electrode, thereby forming a hole injection layer (HI) with a thickness of 5 nm. Following the formation of the hole injection layer, a compound HT1 was vapor deposited to form a first hole transport layer (HT) having a thickness of 80 nm. Following the formation of the first hole transport layer, a compound HT2 was evaporated to form a second hole transport layer (also called an electron blocking layer) (EBL) having a thickness of 10 nm. On the second hole transport layer, a compound BH1 (first host material (BH)) and a compound BD1 (dopant material (BD)) were co-deposited so that the proportion of compound BD1 was 2 mass %, thereby forming a first emitting layer with a thickness of 5 nm. On the first emitting layer, compound BH2 (second host material (BH)) and compound BD1 (dopant material (BD)) were co-deposited so that the proportion of compound BD1 was 2 mass %, thereby forming a second emitting layer with a thickness of 20 nm. A compound ET1 was evaporated on the second light-emitting layer to form a first electron-transporting layer (also referred to as a hole-blocking layer) (HBL) with a thickness of 10 nm. A compound ET2 was evaporated on the first electron transport layer to form a second electron transport layer (ET) with a thickness of 15 nm. LiF was evaporated onto the second electron transport layer to form an electron injection layer with a thickness of 1 nm. Metallic Al was vapor-deposited on the electron injection layer to form a cathode with a thickness of 80 nm. The device configuration of Reference Example 1 is shown in simplified form as follows. ITO(130) / HA1(5) / HT1(80) / HT2(10) / BH1:BD1(5,98%:2%) / BH2:BD1(20,98%:2%) / ET1(10) / ET2(15) / LiF(1) / Al(80) The numbers in parentheses indicate the film thickness (unit: nm). Similarly, the percentages in parentheses (98%:2%) indicate the proportions (mass %) of the host material (compound BH1 or compound BH2) and compound BD1 in the first emitting layer or the second emitting layer. The same notation is used hereinafter.
