[0046] [definition] In this specification, hydrogen atoms include isotopes with different numbers of neutrons, namely, protium, deuterium, and tritium.

[0047] In this specification, in the chemical structural formula, hydrogen atoms, i.e. protium atoms, deuterium atoms, or tritium atoms, are bonded at positions not explicitly indicated by symbols such as "R" or "D" representing deuterium atoms.

[0048] In this specification, the number of cyclic carbon atoms refers to the number of carbon atoms in the ring itself of a compound whose atoms are bonded together to form a cyclic structure (e.g., monocyclic compounds, fused-ring compounds, bridged compounds, carbocyclic compounds, and heterocyclic compounds). When the ring is substituted with a substituent, the carbon atoms contained in the substituent are not included in the number of cyclic carbon atoms. The term "number of cyclic carbon atoms" as used below is the same unless otherwise stated. For example, the number of cyclic carbon atoms in a benzene ring is 6, in a naphthalene ring it is 10, in a pyridine ring it is 5, and in a furan ring it is 4. Additionally, for example, the number of cyclic carbon atoms in 9,9-diphenylfluorenyl is 13, and in 9,9'-spirodifluorenyl it is 25.

[0049] Furthermore, when a benzene ring is substituent, for example, with an alkyl group, the number of carbon atoms in that alkyl group is not included in the number of carbon atoms in the ring-forming process of the benzene ring. Therefore, the number of carbon atoms in a benzene ring with a substituent alkyl group is 6. Similarly, when a naphthalene ring is substituent, for example, with an alkyl group, the number of carbon atoms in that alkyl group is not included in the number of carbon atoms in the ring-forming process of the naphthalene ring. Therefore, the number of carbon atoms in a naphthalene ring with a substituent alkyl group is 10.

[0050] In this specification, the number of cyclic atoms refers to the number of atoms constituting the ring itself in compounds (e.g., monocyclic compounds, fused-ring compounds, bridged compounds, carbocyclic compounds, and heterocyclic compounds) whose atoms are bonded to form a cyclic structure (e.g., monocyclic, fused-ring, and ring aggregates). Atoms that do not constitute a ring (e.g., hydrogen atoms that end the bonds of the ring-forming atoms) and atoms contained in substituents when the ring is substituted are not included in the number of cyclic atoms. The term "number of cyclic atoms" as used below is the same unless otherwise stated. For example, the number of cyclic atoms in a pyridine ring is 6, in a quinazoline ring it is 10, and in a furan ring it is 5. For example, the number of hydrogen atoms bonded to the pyridine ring or the number of atoms constituting substituents are not included in the number of cyclic atoms in pyridine. Therefore, the number of cyclic atoms in a pyridine ring bonded with hydrogen atoms or substituents is 6. Additionally, for example, hydrogen atoms bonded to the carbon atoms of the quinazoline ring, or atoms constituting substituents, are not included in the number of cyclic atoms of the quinazoline ring. Therefore, the number of cyclic atoms in a quinazoline ring bonded with hydrogen atoms or substituents is 10.

[0051] In this specification, the phrase "ZZ group with substituted or unsubstituted carbon atoms numbering XX to YY" refers to the number of carbon atoms when the ZZ group is unsubstituted, excluding the number of carbon atoms in substituents. Here, "YY" is greater than "XX", where "XX" refers to an integer greater than 1 and "YY" refers to an integer greater than 2.

[0052] In this specification, the phrase "ZZ group with substituted or unsubstituted atoms of XX to YY" refers to the number of atoms in the ZZ group when it is unsubstituted, excluding the number of atoms in the substituent group when it is substituted. Here, "YY" is greater than "XX", where "XX" is an integer greater than or equal to 1 and "YY" is an integer greater than or equal to 2.

[0053] In this specification, "unsubstituted ZZ group" means "unsubstituted ZZ group" and "substituted ZZ group" means "substituted ZZ group".

[0054] In this specification, "unsubstituted or unsubstituted ZZ group" means that the hydrogen atom in the ZZ group is not replaced by a substituent. The hydrogen atom in the "unsubstituted ZZ group" is a protium atom, a deuterium atom, or a tritium atom.

[0055] Furthermore, in this specification, "substitution" in the case of "substituted or unsubstituted ZZ group" means that one or more hydrogen atoms in the ZZ group are replaced by a substituent. Similarly, "substitution" in the case of "BB group substituted by AA group" also means that one or more hydrogen atoms in the BB group are replaced by an AA group.

[0056] Substituents described in this specification The substituents described in this specification will be explained below.

[0065] Unless otherwise specified in this specification, the number of carbon atoms in the "unsubstituted alkylene" as described in this specification is 1 to 50, preferably 1 to 20, and more preferably 1 to 6.

[0162] • "Cases where bonds form rings" In this specification, the phrase "forming a substituted or unsubstituted monocyclic ring by bonding one or more groups of two or more adjacent elements together, forming a substituted or unsubstituted fused ring by bonding together, or not bonding together" refers to the following: forming a substituted or unsubstituted monocyclic ring by bonding one or more groups of two or more adjacent elements together; forming a substituted or unsubstituted fused ring by bonding one or more groups of two or more adjacent elements together; and not bonding one or more groups of two or more adjacent elements together.

[0163] The following description addresses the cases of "a substituted or unsubstituted monocyclic ring formed by the mutual bonding of one or more groups of two or more adjacent elements" and "a substituted or unsubstituted fused ring formed by the mutual bonding of one or more groups of two or more adjacent elements" (hereinafter, these cases are sometimes collectively referred to as "the case of forming a ring by bonding"). The case of anthracene compounds represented by the following general formula (TEMP-103) with an anthracene ring as the parent skeleton will be used as an example.

[0164] [Chemistry 20] For example, R 921 ~R 930 In the case of "one or more groups consisting of two or more adjacent elements bonded together to form a loop", the group consisting of two adjacent elements that constitutes one group is R. 921 With R 922 group, R 922 With R 923 group, R 923 With R 924 group, R 924 With R 930 group, R 930 With R 925 group, R 925 With R 926 group, R 926 With R927 group, R 927 With R 928 group, R 928 With R 929 The group, and R 929 With R 921 The group.

[0165] The phrase "one or more groups" refers to the fact that two or more groups consisting of two or more adjacent elements can simultaneously form a loop. For example, R 921 With R 922 They bond together to form a ring Q A And at the same time R 925 With R 926 They bond together to form a ring Q B In the case of the anthracene compound represented by the aforementioned general formula (TEMP-103), the anthracene compound is represented by the following general formula (TEMP-104).

[0166] [Chemistry 21] The case of rings formed by "groups consisting of two or more adjacent elements" includes not only the case of group bonding consisting of "two" adjacent elements as in the previous example, but also the case of group bonding consisting of "three or more" adjacent elements. For example, it refers to R. 921 With R 922 They bond together to form a ring Q A And R 922 With R 923 They bond together to form a ring Q C , consisting of 3 adjacent (R) 921 R 922 and R 923 When the groups of elements Q bond together to form a ring, fused together to form an anthracene matrix, the anthracene compound represented by the aforementioned 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 There are a total of R 922 .

[0167] [Chemistry 22] The formed "monocyclic ring" or "fused ring," as a structure consisting only of rings, can be a saturated ring or an unsaturated ring. Even when a "monocyclic ring" or "fused ring" is formed from "one of the groups consisting of two adjacent rings," the "monocyclic ring" or "fused ring" can form a saturated ring or an unsaturated ring. For example, the ring Q formed in the aforementioned general formula (TEMP-104) A and ring Q BEach is either a "single ring" or a "fused ring". Additionally, the ring Q formed in the aforementioned general formula (TEMP-105) A and ring Q C It is a "fused ring". The ring Q of the aforementioned general formula (TEMP-105) A With ring Q C Through ring Q A With ring Q C Fusing together to form fused rings. The ring Q of the aforementioned general formula (TEMP-104) A If it is a benzene ring, then ring Q A It is a single ring. The ring Q of the aforementioned general formula (TEMP-104) A If it is a naphthalene ring, then ring Q A It is a fused ring.

[0168] "Unsaturated rings" include not only aromatic hydrocarbon rings and aromatic heterocycles, but also aliphatic hydrocarbon rings with unsaturated bonds (i.e., double and / or triple bonds) in their ring structure (e.g., cyclohexene, cyclohexadiene, etc.) and non-aromatic heterocycles with unsaturated bonds (e.g., dihydropyran, imidazoline, pyrazoline, quinazonium, indoline, isoindoline, etc.). "Saturated rings" include aliphatic hydrocarbon rings without unsaturated bonds, or non-aromatic heterocycles without unsaturated bonds.

[0169] As a specific example of an aromatic hydrocarbon ring, one can cite a structure in which the group listed as a specific example in example group G1 is end-capped with a hydrogen atom.

[0170] As a specific example of an aromatic heterocycle, the structure in which the aromatic heterocycle group is end-capped with a hydrogen atom can be cited as a specific example in specific example group G2.

[0171] As a specific example of an aliphatic hydrocarbon ring, one can cite the structure in which the group listed as a specific example in example group G6 is end-capped with hydrogen atoms.

[0172] "Ring formation" refers to the formation of a ring solely from multiple atoms of the parent skeleton, or from multiple atoms of the parent skeleton combined with one or more arbitrary atoms. For example, R shown in the aforementioned general formula (TEMP-104) 921 With R 922 The ring Q formed by mutual bonding A It refers to R 921 The carbon atoms and R atoms of the bonded anthracene skeleton 922 The bonded anthracene framework consists of carbon atoms and rings formed with one or more arbitrary atoms. As a specific example, in the case of R... 921 With R 922 Forming ring Q A In the case of R 921 The carbon atoms and R atoms of the bonded anthracene skeleton 922 When the carbon atoms of the bonded anthracene skeleton form a monocyclic unsaturated ring with four carbon atoms, R 921With R 922 The resulting ring is a benzene ring.

[0173] Here, "any atom" is preferably selected from at least one atom chosen from carbon, nitrogen, oxygen, and sulfur, unless otherwise specified in this specification. For any atom (e.g., carbon or nitrogen), bonds that do not form a ring can be terminated by hydrogen atoms or replaced by "any substituents" described later. When any atom other than carbon is included, the resulting ring is a heterocycle.

[0174] Unless otherwise specified in this specification, "one or more arbitrary atoms" constituting a monocyclic or fused ring are preferably two or more and 15 or less, more preferably three or more and 12 or less, and even more preferably three or more and 5 or less.

[0175] Unless otherwise stated in this specification, "monocyclic" is preferred over "fused-ring".

[0176] Unless otherwise stated in this specification, "unsaturated ring" is preferred over "saturated ring".

[0177] Unless otherwise stated in this specification, "monocyclic" is preferably a benzene ring.

[0178] Unless otherwise specified in this specification, the "unsaturated ring" is preferably a benzene ring.

[0179] Unless otherwise stated in this specification, the preferred form is an unsaturated ring consisting of multiple atoms of a parent skeleton and at least 15 atoms selected from carbon, nitrogen, oxygen and sulfur atoms bonded together, forming a substituted or unsubstituted monocyclic ring.

[0180] When a "monocyclic" or "fused-ring" ring has a substituent, the substituent is, for example, "any substituent" as described later. Specific examples of substituents when a "monocyclic" or "fused-ring" ring has a substituent are the substituents described in the section "Substituents described in this specification" above.

[0181] When the above-mentioned "saturated ring" or "unsaturated ring" has a substituent, the substituent is, for example, "any substituent" as described later. Specific examples of the substituents when the above-mentioned "monocyclic ring" or "fused ring" has a substituent are the substituents described in the section "Substituents described in this specification" above.

[0182] The above explains the cases of "a single ring formed by bonding one or more groups of two or more adjacent elements together, whether substituted or unsubstituted" and "a fused ring formed by bonding one or more groups of two or more adjacent elements together, whether substituted or unsubstituted" ("the case of forming a ring by bonding").
