The organic EL element usually includes an organic layer such as a light emitting layer and a charge transport layer, and various organic compound materials suitable for these layers are being developed.

International Publication No. 2020/135953 U.S. Patent Application Publication No. 2019/00675757

Among the light emitting materials used for the organic EL element, the blue light emitting material is not easy to control to express the emission peak wavelength in a desired wavelength band and to make a single peak in the fluorescence spectrum waveform. For example, the compounds disclosed in Patent Documents 1 and 2 all have problems such as a short wavelength as a blue light emitting material and a single light emission peak waveform cannot be obtained, and have more suitable peak wavelengths and waveforms. Materials are required.
An object of the present invention is to provide a compound having an emission peak wavelength of 440 to 480 nm in a fluorescence spectrum waveform and obtaining a single peak waveform.

As a result of diligent research to achieve the above object, the present inventors have generated an emission peak wavelength of 440 to 480 nm by expanding the BN bond region in a compound containing a BN bond. Moreover, they have found that a single peak waveform can be obtained, and completed the present invention.
According to the present invention, the following compounds are provided.

[Definition]
As used herein, hydrogen atoms include isotopes with different numbers of neutrons, namely light hydrogen (protium), deuterium (deuterium), and tritium (tritium).

In the present specification, a hydrogen atom, that is, a light hydrogen atom, a heavy hydrogen atom, or a hydrogen atom is located at a bondable position in which a symbol such as "R" or "D" representing a deuterium atom is not specified in the chemical structural formula. It is assumed that the triple hydrogen atom is bonded.

As used herein, the number of carbon atoms forming a ring constitutes the ring itself of a compound having a structure in which atoms are cyclically bonded (for example, a monocyclic compound, a fused ring compound, a crosslinked compound, a carbocyclic compound, and a heterocyclic compound). Represents the number of carbon atoms among the atoms to be used. When the ring is substituted with a substituent, the carbon contained in the substituent is not included in the number of carbons forming the ring. The "ring-forming carbon number" described below shall be the same unless otherwise stated. For example, the benzene ring has 6 ring-forming carbon atoms, the naphthalene ring has 10 ring-forming carbon atoms, the pyridine ring has 5 ring-forming carbon atoms, and the furan ring has 4 ring-forming carbon atoms. Further, for example, the ring-forming carbon number of the 9,9-diphenylfluorenyl group is 13, and the ring-forming carbon number of the 9,9'-spirobifluorenyl group is 25.
Further, when the benzene ring is substituted with, for example, an alkyl group as a substituent, the carbon number of the alkyl group is not included in the ring-forming carbon number of the benzene ring. Therefore, the ring-forming carbon number of the benzene ring substituted with the alkyl group is 6. Further, when the naphthalene ring is substituted with, for example, an alkyl group as a substituent, the carbon number of the alkyl group is not included in the ring-forming carbon number of the naphthalene ring. Therefore, the ring-forming carbon number of the naphthalene ring substituted with the alkyl group is 10.

In the present specification, the number of ring-forming atoms is a compound having a structure in which atoms are cyclically bonded (for example, a monocycle, a fused ring, and a ring assembly) (for example, a monocyclic compound, a fused ring compound, a crosslinked compound, and a carbocycle). Represents the number of atoms constituting the ring itself of the compound and the heterocyclic compound). Atoms that do not form a ring (for example, a hydrogen atom that terminates the bond of atoms that form a ring) and atoms included in the substituent when the ring is substituted by a substituent are not included in the number of ring-forming atoms. The "number of ring-forming atoms" described below shall be the same unless otherwise stated. For example, the pyridine ring has 6 ring-forming atoms, the quinazoline ring has 10 ring-forming atoms, and the furan ring has 5 ring-forming atoms. For example, the number of hydrogen atoms bonded to the pyridine ring or the number of atoms constituting the substituent is not included in the number of pyridine ring forming atoms. Therefore, the number of ring-forming atoms of the pyridine ring to which the hydrogen atom or the substituent is bonded is 6. Further, for example, a hydrogen atom bonded to a carbon atom of a quinazoline ring or an atom constituting a substituent is not included in the number of ring-forming atoms of the quinazoline ring. Therefore, the number of ring-forming atoms of the quinazoline ring to which a hydrogen atom or a substituent is bonded is 10.

In the present specification, "the number of carbon atoms XX to YY" in the expression "the ZZ group having the number of carbon atoms XX to YY substituted or unsubstituted" represents the number of carbon atoms when the ZZ group is unsubstituted and is substituted. Does not include the carbon number of the substituent in the case. Here, "YY" is larger than "XX", "XX" means an integer of 1 or more, and "YY" means an integer of 2 or more.

In the present specification, "the number of atoms XX to YY" in the expression "the ZZ group having the number of atoms XX to YY substituted or unsubstituted" represents the number of atoms when the ZZ group is unsubstituted and is substituted. Does not include the number of atoms of the substituent in the case. Here, "YY" is larger than "XX", "XX" means an integer of 1 or more, and "YY" means an integer of 2 or more.

In the present specification, the unsubstituted ZZ group represents the case where the "substituted or unsubstituted ZZ group" is the "unsubstituted ZZ group", and the substituted ZZ group is the "substituted or unsubstituted ZZ group". Represents the case where is a "substitution ZZ group".
As used herein, the term "unsubstituted" in the case of "substituted or unsubstituted ZZ group" means that the hydrogen atom in the ZZ group is not replaced with the substituent. The hydrogen atom in the "unsubstituted ZZ group" is a light hydrogen atom, a deuterium atom, or a triple hydrogen atom.
Further, in the present specification, "substitution" in the case of "substituent or unsubstituted ZZ group" means that one or more hydrogen atoms in the ZZ group are replaced with the substituent. Similarly, "substitution" in the case of "BB group substituted with AA group" means that one or more hydrogen atoms in the BB group are replaced with the AA group.

・ "When combining to form a ring"
In the present specification, "one or more sets of two or more adjacent pairs are bonded to each other to form a substituted or unsubstituted single ring, or are bonded to each other to form a substituted or unsubstituted fused ring. "Forming or not binding to each other" means "one or more pairs of two or more adjacent pairs combine with each other to form a substituted or unsubstituted monocycle" and "adjacent". One or more pairs of two or more pairs are bonded to each other to form a substituted or unsubstituted fused ring, and one or more pairs of two or more adjacent pairs are not bonded to each other. "When and means.
In the present specification, "one or more sets of two or more adjacent sets are combined with each other to form a substituted or unsubstituted monocycle", and "one of two or more adjacent sets". Regarding the case where a pair or more are bonded to each other to form a substituted or unsubstituted fused ring (hereinafter, these cases may be collectively referred to as "a case where they are bonded to form a ring"), the following. ,explain. The case of an anthracene compound represented by the following general formula (TEMP-103) in which the mother skeleton is an anthracene ring will be described as an example.

For example, in the case of "one or more sets of two or more adjacent sets of R ₉₂₁ to R ₉₃₀ are combined with each other to form a ring", the set of two adjacent sets is one set. Is a pair of R ₉₂₁ and R ₉₂₂ , a pair of R ₉₂₂ and R ₉₂₃ , a pair of R ₉₂₃ and R ₉₂₄ , a pair of R ₉₂₄ and R ₉₃₀ , a pair of R ₉₃₀ and R ₉₂₅ , and R ₉₂₅ . The pair with R ₉₂₆ , the pair with R ₉₂₆ and R ₉₂₇ , the pair with R ₉₂₇ and R ₉₂₈ , the pair with R ₉₂₈ and R ₉₂₉ , and the pair with R ₉₂₉ and R ₉₂₁ .

The above-mentioned "one or more sets" means that two or more sets of two or more adjacent sets may form a ring at the same time. For example, when R ₉₂₁ and R ₉₂₂ are coupled to each other to form ring Q _A , and at the same time R ₉₂₅ and R ₉₂₆ are coupled to each other to form ring Q _B , the above general formula (TEMP-103) is used. The anthracene compound represented is represented by the following general formula (TEMP-104).

The case where "a set consisting of two or more adjacent" forms a ring is not only the case where the pair consisting of adjacent "two" is combined as in the above example, but also from the adjacent "three or more". Including the case where the pairs are combined. For example, R ₉₂₁ and R ₉₂₂ are coupled to each other to form a ring Q _A , and _{R 922} and R ₉₂₃ are coupled to each other to form a ring QC, and three adjacent to each other (R ₉₂₁ , R). It means a case where a pair consisting of ₉₂₂ and _R923 ) is bonded to each other to form a ring and condensed into an anthracene mother skeleton. In this case, the anthracene compound represented by the general formula (TEMP-103) is described below. It is represented by the general formula (TEMP-105). In the following general formula (TEMP-105), ring _QA and ring _QC share _R922 .

The formed "monocycle" or "condensed ring" may be a saturated ring or an unsaturated ring as the structure of only the formed ring. Even when "a set of two adjacent sets" forms a "monocycle" or a "condensed ring", the "monocycle" or "condensed ring" is a saturated ring or a ring of saturation. An unsaturated ring can be formed. For example, the ring _QA and the ring QB formed in the general formula (TEMP _- 104) are "single ring" or "condensed ring", respectively. Further, the ring Q _A and the ring Q _C formed in the general formula (TEMP-105) are "condensed rings". The ring Q _A and the ring Q _C of the general formula (TEMP-105) are formed into a fused ring by condensing the ring Q _A and the ring Q _C. If the ring QA of the general formula ( _{TMEP -} 104) is a benzene ring, the ring QA is a monocyclic ring. If the ring QA of the general formula ( _{TMEP -} 104) is a naphthalene ring, the ring QA is a fused ring.

The "unsaturated ring" includes an aromatic hydrocarbon ring, an aromatic heterocycle, and an aliphatic hydrocarbon ring having an unsaturated bond, that is, a double bond and / or a triple bond in the ring structure (for example, an unsaturated ring). Cyclohexene, cyclohexadiene, etc.), and non-aromatic heterocycles with unsaturated bonds (eg, dihydropyran, imidazoline, pyrazoline, quinolidine, indolin, isoindrin, etc.). The "saturated ring" includes an aliphatic hydrocarbon ring having no unsaturated bond or a non-aromatic heterocycle having no unsaturated bond.
Specific examples of the aromatic hydrocarbon ring include a structure in which the group given as a specific example in the specific example group G1 is terminated by a hydrogen atom.
Specific examples of the aromatic heterocycle include a structure in which the aromatic heterocyclic group given as a specific example in the specific example group G2 is terminated by a hydrogen atom.
Specific examples of the aliphatic hydrocarbon ring include a structure in which the group given as a specific example in the specific example group G6 is terminated by a hydrogen atom.
By "forming a ring" is meant forming a ring with only a plurality of atoms in the mother skeleton, or with a plurality of atoms in the mother skeleton and one or more arbitrary atoms. For example, the ring QA formed by bonding R ₉₂₁ and _{R 922} to each other, which is represented by the general formula (TEMP-104), has a carbon atom of an anthracene skeleton to which R ₉₂₁ is bonded and an anthracene to which R ₉₂₂ is bonded. It means a ring formed by carbon atoms in the skeleton and one or more arbitrary atoms. As a specific example, in the case of forming a ring QA with _{R 921} and R ₉₂₂ , a carbon atom of an anthracene skeleton to which R ₉₂₁ is bonded, a carbon atom of an anthracen skeleton to which R ₉₂₂ is bonded, and four carbon atoms. When a monocyclic unsaturated ring is formed with, the ring formed by R ₉₂₁ and R ₉₂₂ is a benzene ring.

Here, "arbitrary atom" is preferably at least one atom selected from the group consisting of a carbon atom, a nitrogen atom, an oxygen atom, and a sulfur atom, unless otherwise specified in the present specification. At any atom (for example, in the case of a carbon atom or a nitrogen atom), 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 later. If it contains any atom other than a carbon atom, the ring formed is a heterocycle.
Unless otherwise described herein, the number of "one or more arbitrary atoms" constituting the monocyclic or condensed ring is preferably 2 or more and 15 or less, and more preferably 3 or more and 12 or less. , More preferably 3 or more and 5 or less.
Unless otherwise described herein, the "monocycle" and the "condensed ring" are preferably "monocycles".
Unless otherwise described herein, the "saturated ring" and the "unsaturated ring" are preferably "unsaturated rings".
Unless otherwise stated herein, a "monocycle" is preferably a benzene ring.
Unless otherwise stated herein, the "unsaturated ring" is preferably a benzene ring.
When "one or more pairs of two or more adjacent pairs""bond to each other to form a substituted or unsubstituted monocycle", or "bond to each other to form a substituted or unsubstituted fused ring". In the case of "forming", unless otherwise described herein, preferably one or more pairs of two or more adjacent pairs are bonded to each other to form a plurality of atoms in the matrix and one or more 15 atoms. It forms a substituted or unsubstituted "unsaturated ring" consisting of at least one atom selected from the group consisting of the following carbon atom, nitrogen atom, oxygen atom, and sulfur atom.

When the above-mentioned "monocycle" or "condensed ring" has a substituent, the substituent is, for example, an "arbitrary substituent" described later. Specific examples of the substituent when the above-mentioned "monocycle" or "condensation ring" has a substituent are the substituents described in the above-mentioned "Substituents described in the present specification" section.
When the above-mentioned "saturated ring" or "unsaturated ring" has a substituent, the substituent is, for example, an "arbitrary substituent" described later. Specific examples of the substituent when the above-mentioned "monocycle" or "condensation ring" has a substituent are the substituents described in the above-mentioned "Substituents described in the present specification" section.
The above is the case where "one or more sets of two or more adjacent sets are combined with each other to form a substituted or unsubstituted monocycle" and "one or more sets of two or more adjacent sets". However, it is a description of the case of "bonding to each other to form a substituted or unsubstituted fused ring"("the case of bonding to form a ring").
