Description

Organic electroluminescence element and electronic device

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

[0002] Organic electroluminescent elements (hereinafter sometimes referred to as "organic EL elements") are applied to full-color displays such as 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. According to the statistical law of electron spin, singlet excitons are generated at a rate of 25% and triplet excitons at a rate of 75%. Performance characteristics of organic EL elements include, for example, brightness, emission wavelength, chromaticity, luminous efficiency, driving voltage, and lifetime. For example, Patent Documents 1 and 2 discuss ways to improve the performance of organic EL elements. Patent Document 1 discloses an organic EL element having a hole-transporting region composed of multiple layers. Patent Document 2 discloses an organic EL element having a light-emitting region composed of multiple layers.

[0016] [Definitions] In this specification, hydrogen atoms include isotopes with different numbers of neutrons, namely protium, deuterium, and tritium.

[0017] In this specification, in a chemical structural formula, a hydrogen atom, that is, 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.

[0018] 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. 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 a benzene ring substituted with an alkyl group is 6. Furthermore, when the 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.

[0019] 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 is 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.

[0020] 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" represents 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.

[0021] In this specification, the "number of atoms XX to YY" in the expression "substituted or unsubstituted ZZ group having number of atoms XX to YY" refers to the number of atoms when the ZZ group is unsubstituted, and does not include the number of atoms of substituents 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, an unsubstituted ZZ group refers to the case where a "substituted or unsubstituted ZZ group" is an "unsubstituted ZZ group", and a substituted ZZ group refers to the case where a "substituted or unsubstituted ZZ group" is a "substituted ZZ group". In this specification, "unsubstituted" in the case 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. Furthermore, in this specification, "substituted" in the case 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 case 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.

Unless otherwise specified herein, the number of carbon atoms of an "unsubstituted alkylene group" described herein is 1 to 50, preferably 1 to 20, and more preferably 1 to 6.

[0102] "When bonded to form a ring" In this specification, when "one or more pairs of adjacent groups bond to each other to form a substituted or unsubstituted monocycle, bond to each other to form a substituted or unsubstituted fused ring, or do not bond to each other," it means when "one or more pairs of adjacent groups bond to each other to form a substituted or unsubstituted monocycle," when "one or more pairs of adjacent groups bond to each other to form a substituted or unsubstituted fused ring," and when "one or more pairs of adjacent groups do not bond to each other." In this specification, the cases when "one or more pairs of adjacent groups bond to each other to form a substituted or unsubstituted monocycle" and "one or more pairs of adjacent groups bond to each other to form a substituted or unsubstituted fused ring" (hereinafter, these cases may be collectively referred to as "when bonded to form a ring") will be explained below. An anthracene compound represented by the following general formula (TEMP-103), in which the main skeleton is an anthracene ring, will be described as an example.

[0103]

[0104] For example, R ９２１~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 and R ９２９ and R ９２１ It is paired with.

[0105] The above-mentioned "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 and simultaneously form 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).

[0106]

[0107] The case where a "set of two or more adjacent groups" forms a ring includes not only the case where a set of "two" adjacent groups is bonded as in the above example, but also the case where a set of "three or more" adjacent groups is bonded. For example, R ９２１ and R ９２２ and are bonded to each other to form ring Q Ａ and R ９２２ and R ９２３ and are bonded to each other to form ring Q Ｃ and three adjacent (R ９２１ , R ９２２ and R９２３ 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.

[0108]

[0109] The "monocyclic ring" or "fused ring" formed may be a saturated ring or an unsaturated ring as the structure of only the formed ring. 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". Ａ , and ring Q Ｃ is a "fused ring". Ａ and Tamaki Q Ｃ That is, Ring Q Ａ and Tamaki Q Ｃ The ring Q in the general formula (TMEP-104) is fused to form a fused ring. Ａ is a benzene ring, then ring Q Ａ The ring Q in the general formula (TMEP-104) is a monocyclic ring. Ａ is a naphthalene ring, then ring Q Ａ is a fused ring.

[0110] The term "unsaturated ring" means an aromatic hydrocarbon ring or an aromatic heterocyclic ring. The term "saturated ring" means an aliphatic hydrocarbon ring or a non-aromatic heterocyclic ring. Specific examples of aromatic hydrocarbon rings 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 aromatic heterocyclic rings include structures in which the aromatic heterocyclic groups given as specific examples in the specific example group G2 are terminated with a hydrogen atom.

[0338] In one aspect of the organic EL device according to this embodiment, when the light-emitting region has at least a first light-emitting layer containing a first host material and a second light-emitting layer containing a second host material, in the compound represented by general formula (A1), R １Ｂ ~R ８Ｂ is preferably a hydrogen atom in order to prevent the intermolecular interaction from being inhibited and to suppress the decrease in electron mobility. １Ｂ ~R ８Ｂmay be a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms, or a substituted or unsubstituted heterocyclic group having 5 to 50 ring atoms. One aspect of the organic EL device according to this embodiment may have an anode, a second emitting layer, a first emitting layer, and a cathode in this order, but the order of the first emitting layer and the second emitting layer may be reversed.

Furthermore, when the electron mobility of the first host material is μe(H1) and the electron mobility of the second host material is μe(H2), the relationship μe(H1)>μe(H2) may not be satisfied. When the compound represented by the general formula (A1) is used as the first host material in the first emitting layer, satisfying the relationship μe(H1)>μe(H2) is expected to suppress a decrease in the recombination ability of holes and electrons in the second emitting layer and a decrease in luminous efficiency. Examples of the substituent include a haloalkyl group, an alkenyl group, an alkynyl group, -Si(R ９０１ ) (R ９０２ ) (R ９０３ ), a group represented by —O—(R ９０４ ), a group represented by —S—(R ９０５ ), a group represented by —N(R ９０６ ) (R ９０７ ), an aralkyl group, a group represented by —C(═O)R ８０１ a group represented by -COOR ８０２ In the compound represented by the general formula (A1), the group represented by the formula (A1), the halogen atom, the cyano group, and the nitro group may become bulky, and the alkyl group and the cycloalkyl group may become even bulkier. １Ｂ~R ８Ｂ is preferably not a bulky substituent, is preferably not an alkyl group or a cycloalkyl group, and is preferably not an alkyl group, a cycloalkyl group, a haloalkyl group, an alkenyl group, an alkynyl group, or —Si(R ９０１ ) (R ９０２ ) (R ９０３ ), a group represented by —O—(R ９０４ ), a group represented by —S—(R ９０５ ), a group represented by —N(R ９０６ ) (R ９０７ ), an aralkyl group, a group represented by —C(═O)R ８０１ a group represented by -COOR ８０２ It is more preferable that the aryl group is not a group represented by the formula (I), a halogen atom, a cyano group, or a nitro group.

[0339] In the general formula (A1), R １Ｂ ~R ８Ｂ It is also preferable that the substituent in the case of "substituted or unsubstituted" does not include the above-mentioned substituents that may be bulky, particularly substituted or unsubstituted alkyl groups and substituted or unsubstituted cycloalkyl groups. １Ｂ ~R ８Ｂ In the case of "substituted or unsubstituted" in the above, the substituent does not include a substituted or unsubstituted alkyl group or a substituted or unsubstituted cycloalkyl group, thereby preventing suppression of intermolecular interactions due to the presence of bulky substituents such as alkyl groups and cycloalkyl groups, and preventing a decrease in electron mobility. Furthermore, when such a compound is used as a first host material in the first emitting layer, a decrease in the recombination ability of holes and electrons in the second emitting layer and a decrease in luminous efficiency can be suppressed.

[0340] R, a substituent of the anthracene skeleton １Ｂ ~R ８Ｂ is not a bulky substituent, and R １Ｂ ~R ８Ｂ is more preferably unsubstituted. １Ｂ ~R ８Ｂ is not a bulky substituent, R as a non-bulky substituent １Ｂ ~R８Ｂ When a substituent is bonded to R, the substituent is preferably not a bulky substituent. １Ｂ ~R ８Ｂ The substituent bonded to is preferably not an alkyl group or a cycloalkyl group, and is preferably an alkyl group, a cycloalkyl group, a haloalkyl group, an alkenyl group, an alkynyl group, or —Si(R ９０１ ) (R ９０２ ) (R ９０３ ), a group represented by —O—(R ９０４ ), a group represented by —S—(R ９０５ ), a group represented by —N(R ９０６ ) (R ９０７ ), an aralkyl group, a group represented by —C(═O)R ８０１ a group represented by -COOR ８０２ It is more preferable that the aryl group is not a group represented by the formula (I), a halogen atom, a cyano group, or a nitro group.

[0394] In one aspect of the organic EL element of this embodiment, the light-emitting region consists solely of the first light-emitting layer. In another aspect of the organic EL element of this embodiment, the light-emitting region includes the first light-emitting layer and further a second light-emitting layer. In another aspect of the organic EL element of this embodiment, the light-emitting region consists solely of the first light-emitting layer and the second light-emitting layer.

[0395] In one aspect of the organic EL device according to this embodiment, the emissive region includes at least a first emissive layer containing a first host material and a second emissive layer containing a second host material. The first host material and the second host material are different from each other. When the emissive region includes at least the first emissive layer and the second emissive layer, the luminous efficiency can be improved by utilizing triplet-triplet-annihilation (sometimes referred to as TTA). TTA is a mechanism in which triplet excitons collide with each other to generate singlet excitons. The TTA mechanism is also sometimes referred to as the TTF mechanism, as described in International Publication No. WO 2010 / 134350.

[0396] 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, while 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%. Meanwhile, the behavior of triplet excitons generated within 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) can be calculated as follows: ３ A ＊ When the density of triplet excitons (hereinafter referred to as triplet excitons) increases, the 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, 5３ 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 25% initially generated. In this case, the TTF-derived emission 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 75% of the initially generated triplet excitons (one singlet exciton is generated from two triplet excitons), a very high internal quantum efficiency of 62.5% is obtained by adding 75% × (1 / 2) = 37.5% to the 25% of the initially generated singlet excitons. In this case, the TTF ratio is 37.5 / 62.5 = 60%.

[0397] In one aspect of the organic EL element according to this embodiment, from the viewpoint of realizing the TTF mechanism, the triplet energy T １ (H1) and the triplet energy T １ (H2) preferably satisfy the relationship of the following mathematical formula (Formula 1), and more preferably satisfy the relationship of the following mathematical formula (Formula 2): T １ (H2)>T １ (H1) ...(Math. 1) T １ (H2)-T １ (H1)>0.03 eV (Equation 2)

[0398] In one aspect of the organic EL element according to this embodiment, when the organic EL element has the first light-emitting layer and the second light-emitting layer that satisfy the relationship of the above mathematical formula (Mathematical Formula 1), the luminous efficiency of the element can be improved.

[0399] In one aspect of the organic EL device according to this embodiment, by satisfying the relationship of the above mathematical formula (1), triplet excitons generated by recombination of holes and electrons in the second emitting layer are thought to be less likely to be quenched at the interface between the second emitting layer and the organic layer, even if excess carriers are present at the interface between the second emitting layer and the organic layer directly in contact with the second emitting layer. For example, when the recombination region is locally present at the interface between the second emitting layer and the hole transport layer or the electron blocking layer, quenching by excess electrons is thought to occur. On the other hand, when the recombination region is locally present at the interface between the second emitting layer and the electron transport layer or the hole blocking layer, quenching by excess holes is thought to occur. In one aspect of the organic EL device according to this embodiment, by providing the first emitting layer and the second emitting layer so as to satisfy the relationship of the above mathematical formula (1), triplet excitons generated in the second emitting layer can migrate to the first emitting layer without being quenched by excess carriers, and reverse migration from the first emitting layer to the second emitting layer can be suppressed. As a result, the TTF mechanism is exerted in the first emitting layer, singlet excitons are efficiently generated, and luminous efficiency is improved. In this way, an organic EL device includes a second emitting layer that mainly generates triplet excitons and a first emitting layer that mainly exerts the TTF mechanism by utilizing triplet excitons transferred from the second emitting layer, as different regions, and uses a compound having a smaller triplet energy than the second host material in the second emitting layer as the first host material in the first emitting layer, thereby providing a difference in triplet energy, and luminous efficiency is improved.

[0400] In one aspect of the organic EL element according to this embodiment, the first light-emitting layer and the second light-emitting layer are in direct contact with each other.

[0401] In this specification, a layer structure in which "the first emitting layer and the second emitting layer are in direct contact" may include, for example, any of the following embodiments (LS1), (LS2), and (LS3). (LS1) An embodiment in which a region in which both the first host material and the second host material are mixed is generated during the process of vapor-depositing the compound for the first emitting layer and the compound for the second emitting layer, and this region is present at the interface between the first emitting layer and the second emitting layer. (LS2) An embodiment in which, when the first emitting layer and the second emitting layer contain a light-emitting compound, a region in which the first host material, the second host material, and the light-emitting compound are mixed is generated during the process of vapor-depositing the compound for the first emitting layer and the compound for the second emitting layer, and this region is present at the interface between the first emitting layer and the second emitting layer. (LS3) When the first emitting layer and the second emitting layer contain a light-emitting compound, a region composed of the light-emitting compound, a region composed of the first host material, or a region composed of the second host material is generated during the process of vapor-depositing the compound for the first emitting layer and the compound for the second emitting layer, and the region is present at the interface between the first emitting layer and the second emitting layer.

[0402] (Second Light-Emitting Layer) In the organic EL element according to this embodiment, the second light-emitting layer is preferably the second light-emitting layer described in the third embodiment. In this embodiment, the second host material contained in the second light-emitting layer is a compound represented by general formula (1X) described below. In one aspect of the organic EL element according to this embodiment, the second host material contained in the second light-emitting layer may be a compound other than the compound represented by general formula (1X) described below. In this embodiment, the second host material is not particularly limited, and for example, a compound selected from the group consisting of the first compounds described below can be used. In one aspect of the organic EL element according to this embodiment, the second light-emitting layer contains a second light-emitting compound. The second light-emitting compound is not particularly limited.

[0403] In one aspect of the organic EL element of this embodiment, the second emitting layer contains a second host material and a second emitting compound. In one aspect of the organic EL element of this embodiment, the second emitting compound and the first emitting compound contained in the first emitting layer are the same or different compounds. In one aspect of the organic EL element of this embodiment, the second host material and the first host material contained in the first emitting layer are different compounds. The second emitting compound is preferably a compound that exhibits emission with a maximum peak wavelength of 500 nm or less, more preferably a compound that exhibits emission with a maximum peak wavelength of 430 nm or more and 480 nm or less. The second emitting compound is preferably a fluorescent compound that exhibits fluorescent emission with a maximum peak wavelength of 500 nm or less, more preferably a fluorescent compound that exhibits fluorescent emission with a maximum peak wavelength of 430 nm or more and 480 nm or less. In one aspect of the organic EL element of this embodiment, the second emitting layer contains a second host material and a second emitting compound that exhibits emission with a maximum peak wavelength of 500 nm or less.

[0404] In one aspect of the organic EL element according to this embodiment, the second light-emitting compound has a maximum peak half width of 1 nm to 30 nm. The method for measuring the maximum peak wavelength of the compound is as described above.

[0405] In one aspect of the organic EL device according to this embodiment, the second light-emitting compound is a compound that does not contain an azine ring structure in the molecule.

[0406] In one aspect of the organic EL device according to this embodiment, the second light-emitting compound is preferably not a boron-containing complex, and more preferably not a complex.

[0407] Examples of compounds that can be used in the second light-emitting layer and emit blue fluorescence include pyrene derivatives, styrylamine derivatives, chrysene derivatives, fluoranthene derivatives, fluorene derivatives, diamine derivatives, and triarylamine derivatives.

[0408] In one aspect of the organic EL element according to this embodiment, the second emitting layer does not contain a metal complex. Also, in one aspect of the organic EL element according to this embodiment, the second emitting layer does not contain a boron-containing complex.

[0409] In one aspect of the organic EL element according to this embodiment, the second emitting layer does not contain a phosphorescent material (dopant material). In one aspect of the organic EL element according to this embodiment, the second emitting layer does not contain a heavy metal complex or a phosphorescent rare earth metal complex.

[0410] (Contents of Second Host Material and Second Light-Emitting Compound in Second Light-Emitting Layer) In one aspect of the organic EL element according to this embodiment, the second light-emitting layer contains the light-emitting compound in an amount of 0.5 mass% or more of the total mass of the second light-emitting layer. The second light-emitting layer preferably contains the light-emitting compound 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.

[0411] In one aspect of the organic EL device according to this embodiment, the second emitting layer preferably contains the second host material in an amount of 60% by mass or more, more preferably 70% by mass or more, even more preferably 80% by mass or more, even more preferably 90% by mass or more, and even more preferably 95% by mass or more. The second emitting layer preferably contains the second host material in an amount of 99.5% by mass or less, based on the total mass of the second emitting layer. When the second emitting layer contains a second host material and a second emitting compound, the upper limit of the total content of the second host material and the second emitting compound is 100% by mass.

[0412] In the organic EL device according to this embodiment, the second light-emitting layer may contain a material other than the second host material and the second light-emitting compound. The second light-emitting layer may contain only one type of second host material, or may contain two or more types of second light-emitting compounds.

[0413] In one aspect of the organic EL element according to this embodiment, the triplet energy T １ (D1) and the triplet energy T １ (H1) preferably satisfies the relationship of the following formula (Formula 4A): T １ (D1)>T １ (H1) ...(Math 4A)

[0414] In one aspect of the organic EL element according to this embodiment, the first light-emitting compound and the first host material satisfy the relationship of the above mathematical formula (Mathematical Formula 4A), whereby triplet excitons generated in the second light-emitting layer transfer energy to molecules of the first host material, rather than to the first light-emitting compound having a higher triplet energy, when they move to the first light-emitting layer. Furthermore, triplet excitons generated by recombination of holes and electrons on the first host material do not transfer to the first light-emitting compound having a higher triplet energy. Triplet excitons generated by recombination on molecules of the first light-emitting compound quickly transfer energy to molecules of the first host material. Triplet excitons from the first host material efficiently collide with each other on the first host material due to the TTF phenomenon, generating singlet excitons, without transferring to the first light-emitting compound.

[0415] In one aspect of the organic EL element according to this embodiment, the singlet energy S １ (H1) and the singlet energy S of the first luminescent compound １ (D1) preferably satisfy the relationship of the following mathematical formula (Mathematical Formula 4): １ (H1)>S １ (D1) ... (Equation 4)

[0416] In one aspect of the organic EL element according to this embodiment, the first light-emitting compound and the first host material satisfy the relationship of the above mathematical formula (Mathematical Formula 4), and therefore the singlet energy of the first light-emitting compound is smaller than the singlet energy of the first host material. Therefore, singlet excitons generated by the TTF phenomenon transfer energy from the first host material to the first light-emitting compound and contribute to the emission (preferably fluorescent emission) of the first light-emitting compound.

[0417] (Film Thickness of First and Second Light-Emitting Layers) In one aspect of the organic EL element according to this embodiment, the film thickness of the first light-emitting layer is preferably 5 nm or more, more preferably 15 nm or more. When the light-emitting region includes a second light-emitting layer, a film thickness of the first light-emitting layer of 5 nm or more can easily prevent triplet excitons that have migrated from the second light-emitting layer to the first light-emitting layer from returning to the second light-emitting layer. Furthermore, a film thickness of the first light-emitting layer of 5 nm or more can sufficiently separate triplet excitons from the recombination moiety in the second light-emitting layer. In one aspect of the organic EL element according to this embodiment, the film thickness of the first light-emitting layer is preferably 20 nm or less. A film thickness of the first light-emitting layer of 20 nm or less can improve the density of triplet excitons in the first light-emitting layer, making the TTF phenomenon more likely to occur. In one aspect of the organic EL element according to this embodiment, the film thickness of the first light-emitting layer is preferably 5 nm or more and 20 nm or less.

[0418] In one aspect of the organic EL element according to this embodiment, the thickness of the second emitting layer is preferably 3 nm or more, more preferably 5 nm or more. If the thickness of the second emitting layer is 3 nm or more, the thickness is sufficient to cause recombination of holes and electrons in the second emitting layer. In one aspect of the organic EL element according to this embodiment, the thickness of the second emitting layer is preferably 15 nm or less, more preferably 10 nm or less. If the thickness of the second emitting layer is 15 nm or less, the thickness is sufficiently thin to allow triplet excitons to migrate to the first emitting layer. In one aspect of the organic EL element according to this embodiment, the thickness of the second emitting layer is more preferably 3 nm or more and 15 nm or less.

[0419] [Second Embodiment] The configuration of an organic EL element of a second embodiment will be described. In the description of the second embodiment, the same components as those of the first embodiment will be denoted by the same reference numerals or names, and the description thereof will be omitted or simplified. Furthermore, in the second embodiment, for materials and compounds not specifically mentioned, the same materials and compounds as those described in the first embodiment can be used.

[0420] The organic EL element of the second embodiment includes a cathode, an anode, an emissive region disposed between the cathode and the anode, and a hole-transporting region disposed between the anode and the emissive region, wherein the emissive region includes one or more emissive layers, the hole-transporting region includes one or more anode-side organic layers, and at least one of the one or more emissive layers contains a compound represented by the following general formula (A200), and at least one of the one or more anode-side organic layers contains a compound represented by the following general formula (B2):

[0421] The organic EL element of the second embodiment differs from the organic EL element of the first embodiment in that at least one of the one or more emitting layers contains a compound represented by general formula (A200) and at least one of the one or more anode-side organic layers contains a compound represented by general formula (B2).

[0422] In the organic EL device of the second embodiment, the amine compound (compound represented by general formula (B2)) contained in the hole-transporting region has a structure in which a fluorenyl group is bonded to a nitrogen atom directly or via a linking group, thereby deepening the ionization potential. As a result, hole injection from the hole-transporting layer to the electron-blocking layer or the light-emitting layer is improved. Furthermore, the anthracene derivative (compound represented by general formula (A200)) contained in the light-emitting region has a structure in which a dibenzofuranyl group, a dibenzothiophenyl group, or the like is bonded to the anthracene skeleton directly or via a linking group, thereby shallowing the ionization potential. As a result, hole injection from the electron-blocking layer to the light-emitting layer is improved. Thus, in the second embodiment, since both the hole-transporting region and the light-emitting region contain a compound capable of improving hole injection into the light-emitting layer, it is believed that excitons are efficiently generated in the light-emitting layer and exciton deactivation by excess electrons is suppressed. Therefore, according to the second embodiment, high efficiency and long life of the organic EL device can be achieved. Furthermore, according to the second embodiment, an organic EL device exhibiting good chromaticity (preferably blue emission) can also be achieved. According to the second embodiment, the performance of the organic EL element can be improved. The organic EL element of the second embodiment can be used in electronic devices such as display devices and light-emitting devices.

[0423] <Hole-transporting region> In the organic EL element according to the second embodiment, the hole-transporting region includes one or more anode-side organic layers, and at least one of the one or more anode-side organic layers contains a compound represented by the following general formula (B2):
