Description

[Technical Field]

[0001] This invention relates to compounds, organic electroluminescent elements, and electronic devices. [Background technology]

[0002] Organic electroluminescent elements (hereinafter sometimes referred to as "organic EL elements") are used in full-color displays 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. Then, in the light-emitting layer, the injected holes and electrons recombine 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 are generated at a rate of 75%. Various studies have been conducted on compounds used in organic EL elements to improve their performance (see, for example, Patent Documents 1 to 4). Examples of organic EL element performance include brightness, emission wavelength, chromaticity, luminous efficiency, driving voltage, and lifespan. [Prior art documents] [Patent Documents]

[0015] According to one aspect of the present invention, an electronic device equipped with an organic electroluminescent element according to one aspect of the present invention is provided. [Effects of the Invention]

[0016] According to one aspect of the present invention, a compound that can improve the performance of an organic EL element, an organic electroluminescent element containing the compound, and an electronic device equipped with the organic electroluminescent element can be provided. Furthermore, according to one aspect of the present invention, when used in the anode-side light-emitting layer of an organic electroluminescent element having multiple light-emitting layers stacked together, it is possible to provide a compound that can be expected to provide an element with a good balance between luminous efficiency and lifespan, an organic electroluminescent element that includes the compound in the anode-side light-emitting layer among the multiple light-emitting layers, and an electronic device equipped with the organic electroluminescent element. [Brief explanation of the drawing]

[0017] [Figure 1] This figure shows a schematic configuration of an example of an organic electroluminescent element according to one embodiment of the present invention. [Modes for carrying out the invention]

[0018] [Definition] In this specification, the term "hydrogen atom" includes isotopes with different numbers of neutrons, namely protium, deuterium, and tritium.

[0019] In this specification, in chemical structural formulas, any bondable positions where symbols such as "R" or "D" representing a deuterium atom are not explicitly indicated shall be assumed to be bonded to hydrogen atoms, i.e., light hydrogen atoms, deuterium atoms, or tritium atoms.

[0020] In this specification, the ring-forming carbon number refers to the number of carbon atoms among the atoms constituting the ring itself in a compound with a structure in which atoms are bonded in a ring (e.g., monocyclic compounds, fused ring compounds, crosslinked compounds, carbocyclic compounds, and heterocyclic compounds). If the ring is substituted by a substituent, the carbon atoms in the substituent are not included in the ring-forming carbon number. The same applies to the "ring-forming carbon number" described below unless otherwise specified. For example, a benzene ring has 6 ring-forming carbon atoms, a naphthalene ring has 10 ring-forming carbon atoms, a pyridine ring has 5 ring-forming carbon atoms, and a furan ring has 4 ring-forming carbon atoms. Also, 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. Furthermore, when a benzene ring is substituted with an alkyl group, for example, the number of carbon atoms in that alkyl group is not included in the number of ring-forming carbon atoms of the benzene ring. Therefore, the number of ring-forming carbon atoms in a benzene ring substituted with an alkyl group is 6. Similarly, when a naphthalene ring is substituted with an alkyl group, for example, the number of carbon atoms in that alkyl group is not included in the number of ring-forming carbon atoms of the naphthalene ring. Therefore, the number of ring-forming carbon atoms in a naphthalene ring substituted with an alkyl group is 10.

[0021] In this specification, the number of ring-forming atoms refers to the number of atoms that constitute the ring itself in compounds with a ring-bonded structure (e.g., monocyclic compounds, fused rings, and ring aggregates) (e.g., monocyclic compounds, fused ring compounds, bridged compounds, carbocyclic compounds, and heterocyclic compounds). Atoms that do not constitute a ring (e.g., hydrogen atoms that terminate the bonds of ring-forming atoms) and atoms included in substituents when the ring is substituted by substituents are not included in the number of ring-forming atoms. The same applies to "number of ring-forming atoms" as described below unless otherwise specified. For example, the number of ring-forming atoms in a pyridine ring is 6, the number of ring-forming atoms in a quinazoline ring is 10, and the number of ring-forming atoms in a furan ring is 5. For example, the number of hydrogen atoms bonded to a pyridine ring, or the number of atoms constituting substituents, are not included in the number of pyridine ring-forming atoms. Therefore, the number of ring-forming atoms in a pyridine ring to which hydrogen atoms or substituents are bonded is 6. Furthermore, for example, hydrogen atoms bonded to the carbon atom of the quinazoline ring, or atoms constituting substituents, are not included in the number of ring-forming atoms of the quinazoline ring. Therefore, the number of ring-forming atoms of a quinazoline ring to which hydrogen atoms or substituents are bonded is 10.

[0022] In this specification, the expression "substituted or unsubstituted ZZ group having XX to YY carbon atoms" means that "XX to YY carbon atoms" represents the number of carbon atoms when the ZZ group is unsubstituted, and does not include the number of carbon atoms of substituents when it is substituted. Here, "YY" is greater than "XX", "XX" means an integer of 1 or more, and "YY" means an integer of 2 or more.

[0023] In this specification, the expression "ZZ group with substituted or unsubstituted atoms of XX to YY" means that "atom count XX to YY" represents the number of atoms when the ZZ group is unsubstituted, and does not include the number of substituent atoms when it is substituted. Here, "YY" is greater than "XX", where "XX" is an integer of 1 or more, and "YY" is an integer of 2 or more.

[0024] In this specification, an unsubstituted ZZ group refers to a case where "substituted or unsubstituted ZZ group" is "unsubstituted ZZ group," and a substituted ZZ group refers to a case where "substituted or unsubstituted ZZ group" is "substituted ZZ group." In this specification, "unsubstituted" in the context of a "substituted or unsubstituted ZZ group" means that the hydrogen atoms in the ZZ group are not replaced by substituents. The hydrogen atoms in an "unsubstituted ZZ group" are light hydrogen atoms, deuterium atoms, or tritium atoms. Furthermore, in this specification, "substituted" in the context of "substituted or unsubstituted ZZ group" means that one or more hydrogen atoms in the ZZ group are replaced by a substituent. Similarly, "substituted" in the context of "BB group substituted with AA group" means that one or more hydrogen atoms in the BB group are replaced by an AA group.

[0106] For example, R921 ~R 930 In the case where "one or more pairs of adjacent groups are joined together to form a ring," the pairs of adjacent groups that make up one set are R 921 and R 922 The pair, R 922 and R 923 The pair, R 923 and R 924 The pair, R 924 and R 930 The pair, R 930 and R 925 The pair, R 925 and R 926 The pair, R 926 and R 927 The pair, R 927 and R 928 The pair, R 928 and R 929 The pair with, and R 929 and R 921 They are a pair.

[0107] The phrase "one or more pairs" above means that two or more pairs of adjacent pairs may simultaneously form a ring. For example, R 921 and R 922 and are joined to form a ring Q A Forms R 925 and R 926 and are joined to form a ring Q B If the above general formula (TEMP-103) is formed, the anthracene compound represented by the above general formula (TEMP-104) is represented by the following general formula (TEMP-104).

[0108] [ka]

[0109] The case where "two or more adjacent elements form a ring" includes not only cases where two adjacent elements are joined, as in the example above, but also cases where three or more adjacent elements are joined. For example, R 921 and R 922 and are joined to form a ring Q A Forms R 922 and R923 and are joined to form a ring Q C It forms three adjacent (R 921 , R 922 and R 923 This refers to the case where a set consisting of ) is bonded to each other to form a ring and condenses onto the anthracene matrix skeleton, in which case the anthracene compound represented by the above general formula (TEMP-103) is represented by the following general formula (TEMP-105). In the following general formula (TEMP-105), ring Q A and ring Q C R 922 Share.

[0110] [ka]

[0111] The formed "mono-ring" or "condensed-ring" may be saturated or unsaturated, based solely on the structure of the formed ring. Even when "a pair of adjacent rings" forms a "mono-ring" or "condensed-ring," the "mono-ring" or "condensed-ring" can be saturated or unsaturated. For example, ring Q formed in the general formula (TEMP-104) A and ring Q B These are, respectively, a "single ring" or a "condensed ring". Also, ring Q formed in the general formula (TEMP-105) is A , and ring Q C This is a "condensed ring". The ring Q of the general formula (TEMP-105) A and Q C This refers to the Q environment. A and Q C The ring Q of the general formula (TMEP-104) is formed by the condensation of the two rings. A If it is a benzene ring, then ring Q A It is a single ring. The ring Q of the general formula (TMEP-104) A If it is a naphthalene ring, then ring Q A It is a condensed ring.

[0112] An "unsaturated ring" refers to an aromatic hydrocarbon ring or an aromatic heterocycle. A "saturated ring" refers to an aliphatic hydrocarbon ring or a non-aromatic heterocycle. Specific examples of aromatic hydrocarbon rings include structures in which the groups listed as examples in specific example group G1 are terminated by hydrogen atoms. A concrete example of an aromatic heterocycle is the structure in which the aromatic heterocycle group listed as a concrete example in concrete example group G2 is terminated by a hydrogen atom. Specific examples of aliphatic hydrocarbon rings include structures in which the groups listed as examples in example group G6 are terminated by hydrogen atoms. "To form a ring" means to form a ring with only multiple atoms of the parent skeleton, or with multiple atoms of the parent skeleton and one or more additional arbitrary elements. For example, as shown in the general formula (TEMP-104), 921 and R 922 A ring Q is formed when these two elements are bonded together. A R 921 The carbon atoms of the anthracene skeleton to which R is bonded, 922 It refers to a ring formed by the carbon atoms of the anthracene skeleton to which the R atoms are bonded, and one or more arbitrary elements. A specific example is R 921 and R 922 And the environment Q A When forming R 921 The carbon atoms of the anthracene skeleton to which R is bonded, 922 When the carbon atoms of the anthracene skeleton bonded to the four carbon atoms form a monocyclic unsaturated ring, R 921 and R 922 The ring formed by these two is a benzene ring.

[0113] Here, "any element" is preferably at least one element selected from the group consisting of carbon, nitrogen, oxygen, and sulfur, unless otherwise specified herein. In any element (for example, carbon or nitrogen), bonds that do not form a ring may be terminated with a hydrogen atom or the like, or substituted with "any substituent" as described later. If any element other than carbon is included, the formed ring is a heterocycle. The "one or more arbitrary elements" constituting the monoring or fused ring are preferably 2 to 15, more preferably 3 to 12, and even more preferably 3 to 5, unless otherwise specified herein. Unless otherwise specified herein, the preferred form is a "mono-ring" and a "condensed ring." Unless otherwise specified herein, the "unsaturated ring" is preferred over the "saturated ring". Unless otherwise specified herein, “monocyclic” is preferably a benzene ring. Unless otherwise specified herein, the “unsaturated ring” is preferably a benzene ring. When "one or more sets of two or more adjacent elements" "bond to each other to form a substituted or unsubstituted monoring" or "bond to each other to form a substituted or unsubstituted fused ring", unless otherwise specified herein, preferably, one or more sets of two or more adjacent elements bond to each other to form a substituted or unsubstituted "unsaturated ring" consisting of multiple atoms of the parent skeleton and at least one element selected from the group consisting of carbon, nitrogen, oxygen, and sulfur elements, ranging from one to fifteen.

[0114] When the above-mentioned "monocyclic ring" or "fused ring" has substituents, the substituents are, for example, "any substituents" as described later. Specific examples of substituents when the above-mentioned "monocyclic ring" or "fused ring" has substituents are the substituents described in the section "Substituents as described herein" above. When the above-mentioned "saturated ring" or "unsaturated ring" has substituents, the substituents are, for example, "any substituents" as described later. Specific examples of substituents when the above-mentioned "mono-ring" or "fused ring" has substituents are the substituents described in the section "Substituents as described herein" above. The above explains the cases in which "one or more pairs of adjacent elements combine to form a substituted or unsubstituted monoring" and "one or more pairs of adjacent elements combine to form a substituted or unsubstituted fused ring" ("the case of combining to form a ring").

[0922] The method for measuring the main peak wavelength of a compound is as follows: 10 -6 mol / L or more 10 -5 Prepare a toluene solution with a concentration of mol / L or less and place it in a quartz cell. Measure the emission spectrum of this sample at room temperature (300K) (vertical axis: emission intensity, horizontal axis: wavelength). 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 measuring device is not limited to the device used here. In the emission spectrum, the peak wavelength of the emission spectrum at which the emission intensity is maximum is defined as the primary emission peak wavelength.

Measure the absorption spectrum of this sample at room temperature (300K) (vertical axis: absorption intensity, horizontal axis: wavelength). Draw a tangent line to the falling edge of the absorption spectrum at longer wavelengths, and substitute the wavelength value λedge [nm] at the intersection of the tangent line and the horizontal axis into the following conversion formula (F2) to calculate the singlet energy. Conversion formula (F2): S1[eV]=1239.85 / λedge Examples of absorption spectrum measuring devices include, but are not limited to, Hitachi's spectrophotometer (device name: U3310).

[0928] The tangent to the falling edge of an absorption spectrum on the longer wavelength side is drawn as follows: Consider the tangents at each point on the spectral curve as we move along the spectral curve in the longer wavelength direction from the maximum value on the longest wavelength side of the absorption spectrum. 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 value of the slope is minimized on the longest wavelength side (except when the absorbance is 0.1 or less) is taken as the tangent to the falling edge of the absorption spectrum on the longer wavelength side.

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

The content of the fourth compound is preferably 1% by mass or more and 10% by mass or less, more preferably 1% by mass or more and 7% by mass or less, and even more preferably 1% by mass or more and 5% by mass or less. However, the upper limit of the total content of the second compound and the fourth compound in the second light-emitting layer is 100% by mass.

[0937] This embodiment does not exclude the possibility that the second light-emitting layer may contain materials other than the second compound and the fourth compound. The second light-emitting layer may contain only one type of the second compound, or two or more types. The second light-emitting layer may contain only one type of the fourth compound, or two or more types.

[0938] The configuration of the organic EL element will be explained further below. In the following text, symbols may be omitted.

[0939] (substrate) The substrate is used as a support for the organic EL element. Examples of substrates include glass, quartz, and plastic. A flexible substrate may also be used. A flexible substrate is a substrate that can be bent (flexible), such as a plastic substrate. Examples of materials for forming a plastic substrate include polycarbonate, polyarylate, polyethersulfone, polypropylene, polyester, polyvinyl fluoride, polyvinyl chloride, polyimide, and polyethylene naphthalate. An inorganic vapor-deposited film may also be used.

[0940] (anode) For the anode formed on the substrate, it is preferable to use a metal, alloy, electrically conductive compound, or mixture thereof with a large work function (specifically, 4.0 eV or more). Specifically, examples include indium tin oxide (ITO), indium tin oxide containing silicon or silicon oxide, indium zinc oxide, tungsten oxide, indium oxide containing zinc oxide, graphene, etc. 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 metallic materials (e.g., titanium nitride).

[0941] These materials are typically deposited by sputtering. For example, indium oxide-zinc oxide can be formed by sputtering using a target containing 1% to 10% by mass of zinc oxide relative to indium oxide. Similarly, indium oxide containing tungsten oxide and zinc oxide can be formed by sputtering using a target containing 0.5% to 5% by mass of tungsten oxide and 0.1% to 1% by mass of zinc oxide relative to indium oxide. Other methods such as vacuum deposition, coating, inkjet, and spin coating may also be used.

[0942] Of the EL layers formed on the anode, the hole injection layer formed in contact with the anode is formed using a composite material that facilitates hole injection regardless of the anode's work function. Therefore, any material suitable for electrode materials (e.g., metals, alloys, electrically conductive compounds, and mixtures thereof, as well as elements belonging to Group 1 or Group 2 of the periodic table) can be used.

[0943] Materials with low work functions, such as elements belonging to Group 1 or Group 2 of the periodic table, namely alkali metals such as lithium (Li) and cesium (Cs), and alkaline earth metals such as magnesium (Mg), calcium (Ca), and strontium (Sr), as well as alloys containing these (e.g., MgAg, AlLi), rare earth metals such as europium (Eu) and ytterbium (Yb), and alloys containing these, can also be used. When forming an anode using alkali metals, alkaline earth metals, or alloys containing these, vacuum deposition or sputtering methods can be used. Furthermore, when using silver paste or similar materials, coating methods or inkjet methods can be employed.

[0944] (cathode) For the cathode, it is preferable to use metals, alloys, electrically conductive compounds, and mixtures thereof with a small work function (specifically, 3.8 eV or less). Specific examples of such cathode materials include elements belonging to Group 1 or Group 2 of the periodic table, namely alkali metals such as lithium (Li) and cesium (Cs), alkaline earth metals such as magnesium (Mg), calcium (Ca), and strontium (Sr), and alloys containing these (e.g., MgAg, AlLi), rare earth metals such as europium (Eu) and ytterbium (Yb), and alloys containing these.

[0945] Furthermore, when forming a cathode using alkali metals, alkaline earth metals, or alloys containing these, vacuum deposition or sputtering methods can be used. Additionally, when using silver paste or similar materials, coating or inkjet methods can be employed.

[0946] Furthermore, by providing an electron injection layer, cathodes can be formed using various conductive materials such as Al, Ag, ITO, graphene, silicon, or indium tin oxide containing silicon oxide, regardless of the magnitude of the work function. These conductive materials can be deposited using methods such as sputtering, inkjet printing, or spin coating.

[0947] (Hole injection layer) The hole injection layer is a layer containing a material with high hole injection properties. Suitable materials with high hole injection properties include molybdenum oxide, titanium oxide, vanadium oxide, rhenium oxide, ruthenium oxide, chromium oxide, zirconium oxide, hafnium oxide, tantalum oxide, silver oxide, tungsten oxide, and manganese oxide.

[0948] Furthermore, substances with high hole injection potential include low-molecular-weight organic compounds such as 4,4',4''-tris(N,N-diphenylamino)triphenylamine (abbreviated as TDATA), 4,4',4''-tris[N-(3-methylphenyl)-N-phenylamino]triphenylamine (abbreviated as MTDATA), 4,4'-bis[N-(4-diphenylaminophenyl)-N-phenylamino]biphenyl (abbreviated as DPAB), 4,4'-bis(N-{4-[N'-(3-methylphenyl)-N'-phenylamino]phenyl}-N-phenylamino)biphenyl (abbreviated as DNTPD), and 1,3,5-tris[N-(4-diphenylaminophenyl)-N-phenylamino] Aromatic amine compounds such as [phenylaminobenzene] (abbreviated as DPA3B), 3-[N-(9-phenylcarbazole-3-yl)-N-phenylamino]-9-phenylcarbazole (abbreviated as PCzPCA1), 3,6-bis[N-(9-phenylcarbazole-3-yl)-N-phenylamino]-9-phenylcarbazole (abbreviated as PCzPCA2), and 3-[N-(1-naphthyl)-N-(9-phenylcarbazole-3-yl)amino]-9-phenylcarbazole (abbreviated as PCzPCN1) are also examples, as is dipyradino[2,3-f:20,30-h]quinoxaline-2,3,6,7,10,11-hexacarbonnitrile (HAT-CN).

[0949] Furthermore, polymer compounds (oligomers, dendrimers, polymers, etc.) can also be used as materials with high hole injection properties. Examples of polymer compounds include poly(N-vinylcarbazole) (abbreviated as PVK), poly(4-vinyltriphenylamine) (abbreviated as PVTPA), poly[N-(4-{N'-[4-(4-diphenylamino)phenyl]phenyl-N'-phenylamino}phenyl)methacrylamide] (abbreviated as PTPDMA), and poly[N,N'-bis(4-butylphenyl)-N,N'-bis(phenyl)benzidine] (abbreviated as Poly-TPD). In addition, polymer compounds to which acids such as poly(3,4-ethylenedioxythiophene) / poly(styrenesulfonic acid) (PEDOT / PSS) and polyaniline / poly(styrenesulfonic acid) (PAni / PSS) have been added can also be used.

[0950] (Hole transport layer) The hole transport layer is a layer containing a substance with high hole transport properties. Aromatic amine compounds, carbazole derivatives, anthracene derivatives, etc., can be used in the hole transport layer. Specifically, 4,4'-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (abbreviated as NPB), N,N'-bis(3-methylphenyl)-N,N'-diphenyl-[1,1'-biphenyl]-4,4'-diamine (abbreviated as TPD), 4-phenyl-4'-(9-phenylfluoren-9-yl)triphenylamine (abbreviated as BAFLP), 4,4'-bis[N-(9,9-dimethylfluoren-2-yl)-N-phenylamino]biphenyl Aromatic amine compounds such as phenyl (abbreviated as DFLDPBi), 4,4',4''-tris(N,N-diphenylamino)triphenylamine (abbreviated as TDATA), 4,4',4''-tris[N-(3-methylphenyl)-N-phenylamino]triphenylamine (abbreviated as MTDATA), and 4,4'-bis[N-(spiro-9,9'-bifluoren-2-yl)-N-phenylamino]biphenyl (abbreviated as BSPB) can be used. The substances described here are mainly 10 -6 cm 2 It is a substance having a hole mobility of / (V·s) or greater.

[0951] The hole transport layer may use carbazole derivatives such as CBP, 9-[4-(N-carbazolyl)]phenyl-10-phenylanthracene (CzPA), and 9-phenyl-3-[4-(10-phenyl-9-anthryl)phenyl]-9H-carbazole (PCzPA), or anthracene derivatives such as t-BuDNA, DNA, and DPAnth. High molecular weight compounds such as poly(N-vinylcarbazole) (abbreviated as PVK) and poly(4-vinyltriphenylamine) (abbreviated as PVTPA) can also be used.

[0952] However, other materials may be used as long as they have higher hole transport capabilities than electron transport capabilities. Furthermore, the layer containing the material with high hole transport capabilities may be a single layer, or it may consist of two or more layers of the above-mentioned material stacked together.

[0953] (electron transport layer) The electron transport layer is a layer containing a material with high electron transport properties. The electron transport layer can contain: 1) metal complexes such as aluminum complexes, beryllium complexes, and zinc complexes; 2) heteroaromatic compounds such as imidazole derivatives, benzimidazole derivatives, azine derivatives, carbazole derivatives, and phenanthroline derivatives; and 3) polymer compounds. Specifically, low-molecular-weight organic compounds such as Alq, tris(4-methyl-8-quinolinolato)aluminum (abbreviated as Almq3), bis(10-hydroxybenzo[h]quinolinato)beryllium (abbreviated as BeBq2), BAlq, Znq, ZnPBO, and ZnBTZ, among others, can be used. In addition to metal complexes, there are also 2-(4-biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole (abbreviation: PBD), 1,3-bis[5-(ptert-butylphenyl)-1,3,4-oxadiazole-2-yl]benzene (abbreviation: OXD-7), 3-(4-tert-butylphenyl)-4-phenyl-5-(4-biphenylyl)-1,2,4-triazole (abbreviation: Heteroaromatic compounds such as (TAZ), 3-(4-tert-butylphenyl)-4-(4-ethylphenyl)-5-(4-biphenylyl)-1,2,4-triazole (abbreviated as p-EtTAZ), vasophenanthroline (abbreviated as BPhen), vasocuproin (abbreviated as BCP), and 4,4'-bis(5-methylbenzoxazole-2-yl)stilbene (abbreviated as BzOs) can also be used. In this embodiment, benzimidazole compounds can be suitably used. The substances described herein are mainly 10 -6 cm 2 The material has an electron mobility of 1 / (V·s) or greater. However, any material with higher electron transport properties than hole transport properties may be used as the electron transport layer. Furthermore, the electron transport layer may consist of a single layer, or it may consist of two or more layers of the above material stacked together.

[0954] Specific examples of compounds that can be used in electron transport layers include the following compounds. However, the present invention is not limited to these specific examples of compounds.

[0955] [ka]

[0956] Furthermore, polymer compounds can also be used in the electron transport layer. For example, poly[(9,9-dihexylfluorene-2,7-diyl)-co-(pyridine-3,5-diyl)] (abbreviated as PF-Py) and poly[(9,9-dioctylfluorene-2,7-diyl)-co-(2,2'-bipyridine-6,6'-diyl)] (abbreviated as PF-BPy) can be used.

[0957] (electron injection layer) The electron injection layer is a layer containing a material with high electron injection potential. The electron injection layer can contain alkali metals, alkaline earth metals, or compounds thereof, such as lithium (Li), cesium (Cs), calcium (Ca), lithium fluoride (LiF), cesium fluoride (CsF), calcium fluoride (CaF2), and lithium oxide (LiOx). Alternatively, a material containing an alkali metal, alkaline earth metal, or compound thereof in an electron-transporting material, specifically one containing magnesium (Mg) in Alq, may also be used. In this case, electron injection from the cathode can be performed more efficiently.

[0958] Alternatively, a composite material formed by mixing an organic compound and an electron donor may be used in the electron injection layer. Such a composite material exhibits 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, and specifically, for example, the substances that constitute the electron transport layer described above (metal complexes, heteroaromatic compounds, etc.) can be used. The electron donor can be any substance that exhibits electron-donating properties to the organic compound. Specifically, alkali metals, alkaline earth metals, and rare earth metals are preferred, such as lithium, cesium, magnesium, calcium, erbium, and ytterbium. Alkali metal oxides and alkaline earth metal oxides are also preferred, such as lithium oxide, calcium oxide, and barium oxide. Lewis bases such as magnesium oxide can also be used. Organic compounds such as tetrathiafulvalene (abbreviated as TTF) can also be used.

[0959] (Layer formation method) The method for forming each layer of the organic EL element in this embodiment is not limited to those specifically mentioned above, but known methods such as dry deposition methods such as vacuum deposition, sputtering, plasma deposition, and ion plating, and wet deposition methods such as spin coating, dipping, flow coating, and inkjet deposition can be employed.

[0960] (film thickness) The film thickness of each organic layer in the organic EL element of this embodiment is not limited unless otherwise specifically mentioned above. Generally, if the film thickness is too thin, defects such as pinholes are likely to occur, and if the film thickness is too thick, a high applied voltage is required, resulting in poor efficiency. Therefore, the film thickness of each organic layer in the organic EL element is usually preferably in the range of a few nanometers to 1 μm.

[0961] (Emission wavelength of organic EL elements) In this embodiment, the organic electroluminescent element preferably emits light with a main peak wavelength of 430 nm to 480 nm when the element is driven. The main peak wavelength of light emitted by the organic EL element during element drive is measured as follows: Current density is 10 mA / cm². 2 The spectral radiance spectrum of an organic EL element is measured using a spectroradiometer CS-2000 (manufactured by Konica Minolta) when a voltage is applied to the element in such a manner. The peak wavelength of the emission spectrum with the maximum emission intensity is measured from the obtained spectral radiance spectrum and defined as the main peak wavelength (unit: nm).

[0962] The organic EL element according to this embodiment can improve element performance. Furthermore, in the organic EL element according to the embodiment in which multiple light-emitting layers are stacked, since the light-emitting layer on the anode side (first light-emitting layer) contains the compound according to the first embodiment, it is expected that a good balance between luminous efficiency and lifespan will be achieved.

[0963] [Fourth Embodiment] (electronic equipment) The electronic device according to this embodiment is equipped with an organic EL element according to any of the embodiments described above. Examples of electronic devices include display devices and light-emitting devices. Examples of display devices include display components (e.g., organic EL panel modules), televisions, mobile phones, tablets, and personal computers. Examples of light-emitting devices include lighting and vehicle lights.

[0964] [Changes to the embodiment] Furthermore, the present invention is not limited to the embodiments described above, and any modifications, improvements, etc., that can achieve the objectives of the present invention are included in the present invention.

[0965] For example, the light-emitting layer is not limited to one layer or two layers, but may consist of more than two stacked light-emitting layers. When an organic EL element has multiple light-emitting layers, it is sufficient if one light-emitting layer satisfies the conditions described in the above embodiment, or if two light-emitting layers satisfy the conditions described in the above embodiment. For example, the other light-emitting layers may be fluorescent light-emitting layers, or phosphorescent light-emitting layers that utilize light emission due to electron transitions from a triplet excited state to a direct ground state. Furthermore, if the organic EL element has multiple light-emitting layers, these light-emitting layers may be arranged adjacent to each other, or it may be a so-called tandem type organic EL element in which multiple light-emitting units are stacked with an intermediate layer in between.

[0966] Alternatively, for example, a barrier layer may be provided adjacent to at least one of the anode and cathode sides of the light-emitting layer. The barrier layer is preferably positioned in contact with the light-emitting layer and blocks at least one of holes, electrons, and excitons. For example, if a barrier layer is placed in contact with the cathode side of the light-emitting layer, the barrier layer transports electrons and prevents holes from reaching the layer on the cathode side of the barrier layer (e.g., the electron transport layer). If the organic EL element includes an electron transport layer, it is preferable to include the barrier layer between the light-emitting layer and the electron transport layer. Furthermore, if a barrier layer is placed in contact with the anode side of the light-emitting layer, the barrier layer transports holes and prevents electrons from reaching the layer on the anode side of the barrier layer (for example, a hole transport layer). If the organic EL element includes a hole transport layer, it is preferable to include the barrier layer between the light-emitting layer and the hole transport layer. Furthermore, a barrier layer may be provided adjacent to the light-emitting layer to prevent excitation energy from leaking from the light-emitting layer to the surrounding layers. This barrier layer prevents excitons generated in the light-emitting layer from moving to layers closer to the electrodes (for example, electron transport layers and hole transport layers). It is preferable that the light-emitting layer and the barrier layer are bonded together.

[0967] Furthermore, the specific structure and shape in the implementation of the present invention may be other structures, etc., to the extent that the objectives of the present invention can be achieved. [Examples]
