Abstract
Description
Technical Field
[0001] This invention relates to novel compounds and organic electroluminescent elements. Background Technology
[0002] When a voltage is applied to an organic electroluminescent element (hereinafter sometimes referred to as an organic EL element), holes are injected into the light-emitting layer from the anode, and electrons are injected from the cathode. Furthermore, in the light-emitting layer, the injected holes and electrons recombine to form excitons.
[0003] In the past, the performance of organic EL devices has been insufficient. While improvements in materials used in organic EL devices have been made to enhance performance, further high-performance applications are still required. In particular, improving the lifespan of organic EL devices is a crucial issue related to the lifespan of practically applicable products, thus demanding materials capable of achieving long lifespans for organic EL devices.
[0004] Patent document 1 discloses the use of compounds with specific structures in the light-emitting layer of organic EL elements.

[0026] [definition]
[0027] In this specification, hydrogen atoms include isotopes with different numbers of neutrons, namely, protium, deuterium, and tritium.
[0028] 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.
[0029] In this specification, the number of cyclic carbon atoms refers to the number of carbon atoms in the atoms constituting the ring itself in a compound whose atoms are bonded into a cyclic structure (e.g., monocyclic compounds, fused-ring compounds, cross-linked 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 specified. 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-diphenylfluorene is 13, and in 9,9'-spirodifluorene is 25.
[0030] Furthermore, when a benzene ring is substituent for, for example, 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 the ring-forming process of a benzene ring with a substituent alkyl group is 6. Similarly, when a naphthalene ring is substituent for, for example, 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 the ring-forming process of a naphthalene ring with a substituent alkyl group is 10.
[0031] 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, cross-linked compounds, carbocyclic compounds, and heterocyclic compounds) whose atoms are bonded into 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 atoms constituting the ring) 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 specified. 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 atoms forming the pyridine ring. Therefore, the number of cyclic atoms in a pyridine ring bonded with hydrogen atoms or substituents is 6. Furthermore, 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.
[0032] In this specification, the phrase "ZZ group with substituted or unsubstituted carbon atoms numbering XX~YY" refers to the number of carbon atoms when the ZZ group is unsubstituted, excluding the number of carbon atoms in the substituents. Here, "YY" is greater than "XX", where "XX" represents an integer greater than 1 and "YY" represents an integer greater than 2.
[0033] In this specification, the phrase "ZZ group with substituted or unsubstituted atoms XX~YY" refers to the number of atoms when the ZZ group is unsubstituted, excluding the number of atoms of substituents when substituted. Here, "YY" is greater than "XX", where "XX" represents an integer greater than 1 and "YY" represents an integer greater than 2.
[0034] In this specification, "unsubstituted ZZ group" means "unsubstituted ZZ group" and "substituted ZZ group" means "substituted ZZ group".
[0035] In this specification, "unsubstituted or unsubstituted ZZ group" means that the hydrogen atom of 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.
[0036] Furthermore, in this specification, "substitution" in the case of "substituted or unsubstituted ZZ group" means that one or more hydrogen atoms of 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 of the BB group are replaced by an AA group.
[0037] Substituents described in this specification
[0038] The substituents described in this specification will be explained below.
[0039] Unless otherwise specified in this specification, the number of cyclic carbon atoms in the "unsubstituted aryl group" as described in this specification is 6 to 50, preferably 6 to 30, and more preferably 6 to 18.

[0043] Unless otherwise stated in this specification, the number of carbon atoms in the "unsubstituted alkynyl group" described in this specification is 2 to 50, preferably 2 to 20, and more preferably 2 to 6.

[0047] Unless otherwise specified in this specification, the number of carbon atoms in the "unsubstituted alkylene group" as described in this specification is 1 to 50, preferably 1 to 20, and more preferably 1 to 6.

[0413] • "Cases where bonds form rings"
[0414] In this specification, the phrase "one or more groups of two or more adjacent elements bonded together to form a substituted or unsubstituted monocyclic ring, or bonded together to form a substituted or unsubstituted fused ring, or not bonded together" refers to the following: "one or more groups of two or more adjacent elements bonded together to form a substituted or unsubstituted monocyclic ring," "one or more groups of two or more adjacent elements bonded together to form a substituted or unsubstituted fused ring," and "one or more groups of two or more adjacent elements not bonded together."
[0415] The following explanation addresses the cases described in this specification as "forming a substituted or unsubstituted monocyclic ring by bonding one or more groups of two or more adjacent elements together" and "forming a substituted or unsubstituted fused ring by bonding one or more groups of two or more adjacent elements together" (hereinafter sometimes collectively referred to as "forming a ring by bonding"). An example is an anthracene compound represented by the following general formula (TEMP-103) with an anthracene ring as its parent skeleton.
[0416] [Chemistry 20]
[0417]
[0418] For example, R 921 ~R930 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 forms a single 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 R 927 group, R 927 With R 928 group, R 928 With R 929 The group, and R 929 With R 921 The group.
[0419] 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 Meanwhile, R 925 With R 926 They bond together to form a ring Q B In this case, the anthracene compound represented by the aforementioned general formula (TEMP-103) is represented by the following general formula (TEMP-104).
[0420] [Chemistry 21]
[0421]
[0422] The formation of rings from "groups consisting of two or more adjacent elements" includes not only the bonded group of "two" adjacent elements as in the previous example, but also the bonded group 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 923When the groups of components Q bond together to form a ring and fuse with the 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 .
[0423] [Chemistry 22]
[0424]
[0425] The formed "monocyclic ring" or "fused ring" is only a structural feature of the formed ring and can be either a saturated or unsaturated ring. Even when forming a "monocyclic ring" or "fused ring," the "monocyclic ring" or "fused ring" can still form either a saturated or unsaturated ring. For example, the ring Q formed in the aforementioned general formula (TEMP-104) A and ring Q B These are respectively "monocyclic" or "fused-ring". Furthermore, 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 They fuse to form fused rings. If the ring Q of the aforementioned general formula (TMEP-104)... A If it is a benzene ring, then ring Q A It is a single ring. If the ring Q of the aforementioned general formula (TMEP-104) is... A If it is a naphthalene ring, then ring Q A It is a fused ring.
[0426] "Unsaturated rings" include, in addition to aromatic hydrocarbon rings and aromatic heterocycles, aliphatic hydrocarbon rings (e.g., cyclohexene, cyclohexadiene, etc.) with unsaturated bonds, i.e., double and / or triple bonds, 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.
[0427] As a specific example of an aromatic hydrocarbon ring, the structure in specific example group G1, where the group is end-capped with a hydrogen atom, can be cited.
[0428] As a specific example of an aromatic heterocycle, the structure in example group G2 where the aromatic heterocycle group is end-capped with hydrogen atoms can be cited.
[0429] As a specific example of an aliphatic hydrocarbon ring, the structure in example group G6, where the group is end-capped with a hydrogen atom, can be cited.
[0430] "Ring formation" refers to the formation of a ring by multiple atoms of the parent skeleton, or by multiple atoms of the parent skeleton further forming a ring 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 skeleton consists of a ring formed by carbon atoms and one or more arbitrary atoms. As a specific example, 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 bonded anthracene skeleton carbon atoms and four carbon atoms form a monocyclic unsaturated ring, R 921 With R 922 The resulting ring is a benzene ring.
[0431] Unless otherwise stated in this specification, "any atom" is preferably selected from at least one atom chosen from carbon, nitrogen, oxygen, and sulfur. In any atom (e.g., in the case of carbon or nitrogen), bonds that do not form a ring can be capped by hydrogen atoms or substituted by "any substituents" described later. When any atom other than carbon is included, the resulting ring is a heterocycle.

[1217] A washed glass substrate with a transparent electrode is mounted on a substrate support of a vacuum evaporation apparatus. First, HI compound is deposited on the surface where the transparent electrode is formed, covering the transparent electrode, to form a 5 nm thick HI film. This HI film functions as a hole injection layer.
[1218] Following the deposition of the HI film, compound HT1 is then deposited to form an HT1 film with a thickness of 80 nm on the HI film. This HT1 film functions as the first hole transport layer.
[1219] After the HT1 film is formed, compound HT2 is deposited by vapor deposition to form an HT2 film with a thickness of 10 nm on the HT1 film. This HT2 film functions as a second hole transport layer.
[1220] BH-1 (host material) and BD-1 (dopant material) were co-deposited on the HT2 film in such a way that the weight ratio of compound BD-1 reached 2% to form a light-emitting layer with a film thickness of 25 nm.
[1221] Compound HBL was deposited on the emitting layer to form an electron transport layer with a thickness of 10 nm. Compound ET, used as an electron injection material, was then deposited on the electron transport layer to form an electron injection layer with a thickness of 15 nm. LiF was then deposited on the electron injection layer to form a LiF film with a thickness of 1 nm. Metallic Al was then deposited on the LiF film to form a metal cathode with a thickness of 80 nm.
