Description

[Technical field]

[0001] The present invention relates to a novel compound and an organic electroluminescence device. [Background technology]

[0002] When a voltage is applied to an organic electroluminescence element (hereinafter sometimes referred to as an organic EL element), holes are injected from the anode and electrons are injected from the cathode into the light-emitting layer. In the light-emitting layer, the injected holes and electrons recombine to form excitons.

[0003] Conventional organic EL elements still do not have sufficient element performance. Although the materials used in organic EL elements have been gradually improved to enhance element performance, further improvements in performance are required. In particular, improving the lifespan of organic EL elements is an important issue that will lead to the lifespan of practical products, so materials that can realize long-life organic EL elements are required.

[0004] Patent Document 1 discloses the use of a compound having a specific structure in the light-emitting layer of an organic EL device. [Prior art documents] [Patent documents]

[0009] [Figure 1] FIG. 1 is a diagram showing a schematic configuration of an organic EL element according to one embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] [Definition] In this specification, hydrogen atoms include isotopes having different numbers of neutrons, namely protium, deuterium, and tritium.

[0011] In the present specification, in a chemical structural formula, a hydrogen atom, i.e., a protium atom, a deuterium atom, or a tritium atom is assumed to be bonded to a possible bonding position that is not explicitly indicated with a symbol such as "R" or "D" representing a deuterium atom.

[0012] In this specification, the number of ring carbon atoms represents 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 (for example, a monocyclic compound, a condensed ring compound, a bridged compound, a carbocyclic compound, and a heterocyclic compound). When the ring is substituted with a substituent, the carbon contained in the substituent is 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, the number of ring carbon atoms of a 9,9-diphenylfluorenyl group is 13, and the number of ring carbon atoms of a 9,9'-spirobifluorenyl group is 25. In addition, when a 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 number of ring carbon atoms of the benzene ring. Therefore, the number of ring carbon atoms of the benzene ring substituted with an alkyl group is 6. In addition, when a 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 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.

[0013] 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 compound, a fused ring compound, and a ring assembly). The number of ring atoms does not include atoms that do not constitute a ring (e.g., a hydrogen atom that terminates the bond of an atom constituting a ring) or atoms contained in a substituent when the ring is substituted with a substituent. 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 a 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. For example, hydrogen atoms bonded to carbon atoms of a quinazoline ring or atoms constituting a substituent are not included in the number of ring atoms of the quinazoline ring. Therefore, the number of ring atoms of a quinazoline ring to which a hydrogen atom or a substituent is bonded is 10.

[0014] In the present specification, the "number of carbon atoms XX to YY" in the expression "a 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.

[0015] In the present specification, the "number of atoms XX to YY" in the expression "a substituted or unsubstituted ZZ group having the number of atoms XX to YY" represents the number of atoms when the ZZ group is unsubstituted, and does not include the number of 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.

[0016] In this specification, the term "unsubstituted ZZ group" refers to the case where a "substituted or unsubstituted ZZ group" is an "unsubstituted ZZ group", and the term "substituted ZZ group" refers to the case where a "substituted or unsubstituted ZZ group" is a "substituted ZZ group". In the present 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 protium atom, a deuterium atom, or a tritium atom. In the present 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.

[0095] The above is an explanation of "the substituents described in this specification".

[0096] - "When bonded to form a ring" In this specification, the phrase "one or more of a set consisting of two or more 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 are not bonded to each other" means the case where "one or more of a set consisting of two or more adjacent groups bond to each other to form a substituted or unsubstituted monocycle", the case where "one or more of a set consisting of two or more adjacent groups bond to each other to form a substituted or unsubstituted fused ring", and the case where "one or more of a set consisting of two or more adjacent groups are not bonded to each other". In this specification, the cases where "one or more of a set of two or more adjacent rings are bonded to each other to form a substituted or unsubstituted monocyclic ring" and "one or more of a set of two or more adjacent rings are bonded to each other to form a substituted or unsubstituted condensed ring" (hereinafter, these cases may be collectively referred to as "a case where they are bonded to form a ring") will be explained below. 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 explained as an example.

[0097] [ka]

[0098] For example, R921 ~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," one pair of adjacent two groups is R 921 and R 922 With R 922 and R 923 With R 923 and R 924 With R 924 and R 930 With R 930 and R 925 With R 925 and R 926 With R 926 and R 927 With R 927 and R 928 With R 928 and R 929 and R 929 and R 921 It is paired with .

[0099] The above "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 ring Q A At the same time, R 925 and R 926 and are bonded to ring Q B When the above 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).

[0100] [ka]

[0101] The case where a "set of two or more adjacent units" forms a ring includes not only the case where a set of two adjacent units is bonded as in the previous example, but also the case where a set of three or more adjacent units is bonded. For example, R 921 and R 922 and are bonded to ring Q A and R 922 and R923 and are bonded to ring Q C The three adjacent (R 921 , R 922 and R 923 In this case, the anthracene compound represented by the general formula (TEMP-103) is represented by the following general formula (TEMP-105). In the following general formula (TEMP-105), the ring Q A and Ring Q C is R 922 Share.

[0102] [ka]

[0103] The "monocyclic ring" or "condensed ring" formed may be a saturated or unsaturated ring as the structure of only the ring formed. Even when "one of the pairs of adjacent two" forms a "monocyclic ring" or a "condensed ring", the "monocyclic ring" or the "condensed ring" may form a saturated or unsaturated ring. For example, the ring Q formed in the general formula (TEMP-104) may be a saturated or unsaturated ring. A and Ring Q B are "monocyclic" or "condensed rings". In addition, the ring Q formed in the general formula (TEMP-105) A , and ring Q C is a "fused ring". The ring Q in the above general formula (TEMP-105) A and Kan Q C That is, Ring Q A and Kan Q C The ring Q in the general formula (TMEP-104) is condensed to form a condensed ring. A If is a benzene ring, then ring Q A The ring Q in the general formula (TMEP-104) is a monocyclic ring. A If is a naphthalene ring, then ring Q A is a fused ring.

[0104] The "unsaturated ring" includes aromatic hydrocarbon rings and aromatic heterocycles, as well as aliphatic hydrocarbon rings having an unsaturated bond in the ring structure, i.e., a double bond and / or a triple bond (e.g., cyclohexene, cyclohexadiene, etc.), and non-aromatic heterocycles having an unsaturated bond (e.g., dihydropyran, imidazoline, pyrazoline, quinolizine, indoline, isoindoline, 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 structures in which the groups given as specific examples in the specific example group G1 are terminated with a hydrogen atom. Specific examples of the aromatic heterocycle include structures in which the aromatic heterocyclic groups exemplified as specific examples in the specific example group G2 are terminated with a hydrogen atom. Specific examples of the aliphatic hydrocarbon ring include structures in which the groups given as specific examples in the specific example group G6 are terminated with a hydrogen atom. The term "form a ring" means that a ring is formed only with a plurality of atoms of the parent skeleton, or with a plurality of atoms of the parent skeleton and one or more optional atoms. For example, R 921 and R 922 and are bonded together to form a ring Q A is R 921 The carbon atom of the anthracene skeleton to which R is bonded 922 It means a ring formed by the carbon atom of the anthracene skeleton to which R is bonded and one or more arbitrary atoms. 921 and R 922 Todekan Q A In the case where R 921 The carbon atom of the anthracene skeleton to which R is bonded 922 When the carbon atom of the anthracene skeleton to which R is bonded forms a monocyclic unsaturated ring with four carbon atoms, R 921 and R 922 The ring formed by this is a benzene ring.

[0105] Here, unless otherwise specified in the present specification, the "arbitrary atom" is preferably at least one atom selected from the group consisting of carbon atoms, nitrogen atoms, oxygen atoms, and sulfur atoms. In the arbitrary 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 below. When an arbitrary atom other than a carbon atom is included, the ring formed is a heterocycle. Unless otherwise specified in this specification, the "any one or more atoms" constituting the single ring or the condensed ring is preferably 2 or more and 15 or less, more preferably 3 or more and 12 or less, and even more preferably 3 or more and 5 or less. Unless otherwise specified in this specification, of the "monocyclic ring" and the "condensed ring", the "monocyclic ring" is preferred. Unless otherwise specified in this specification, of the "saturated ring" and the "unsaturated ring", the "unsaturated ring" is preferred. Unless otherwise specified in this specification, a "monocyclic ring" is preferably a benzene ring. Unless otherwise specified in this specification, the "unsaturated ring" is preferably a benzene ring. When "one or more of a set of two or more adjacent rings" "combine with each other to form a substituted or unsubstituted monocyclic ring" or "combine with each other to form a substituted or unsubstituted fused ring", unless otherwise specified in this specification, preferably, one or more of a set of two or more adjacent rings combine with each other to form a substituted or unsubstituted "unsaturated ring" consisting of a plurality of atoms of the parent skeleton and at least one atom selected from the group consisting of 1 to 15 carbon atoms, nitrogen atoms, oxygen atoms, and sulfur atoms.

[0106] When the above-mentioned "monocyclic ring" or "condensed ring" has a substituent, the substituent is, for example, the "optional substituent" described later. When the above-mentioned "monocyclic ring" or "condensed ring" has a substituent, specific examples of the substituent are the substituents described in the above-mentioned section "Substituents described in this specification". When the above-mentioned "saturated ring" or "unsaturated ring" has a substituent, the substituent is, for example, the "optional substituent" described below. When the above-mentioned "monocyclic ring" or "condensed ring" has a substituent, specific examples of the substituent are the substituents described in the above section "Substituents described in this specification". The above is an explanation of the case where "one or more pairs of adjacent groups bond with each other to form a substituted or unsubstituted monocyclic ring" and the case where "one or more pairs of adjacent groups bond with each other to form a substituted or unsubstituted fused ring" ("combined to form a ring").

[0269] In this specification, the term "hole injection / transport layer" means "at least one of a hole injection layer and a hole transport layer", and the term "electron injection / transport layer" means "at least one of an electron injection layer and an electron transport layer".

[0270] Hereinafter, members that can be used in the organic EL device according to one embodiment of the present invention and materials other than the above-mentioned compounds that constitute each layer will be described.

[0271] (substrate) The substrate is used as a support for the light-emitting element. For example, glass, quartz, plastic, etc. can be used as the substrate. A flexible substrate may also be used.

[0276] (Host material for the light-emitting layer) The light-emitting layer may have a structure in which the highly light-emitting substance (guest material) described above is dispersed in another substance (host material). As a substance for dispersing the highly light-emitting substance, various substances can be used in addition to the above-described material used in the present invention (compound represented by formula (10)), and it is preferable to use a substance having a lower lowest unoccupied molecular orbital level (LUMO level) and a lower highest occupied molecular orbital level (HOMO level) than the highly light-emitting substance. Examples of substances (host materials) for dispersing highly luminescent substances include 1) metal complexes such as aluminum complexes, beryllium complexes, and zinc complexes; 2) heterocyclic compounds such as oxadiazole derivatives, benzimidazole derivatives, and phenanthroline derivatives; 3) condensed aromatic compounds such as carbazole derivatives, anthracene derivatives, phenanthrene derivatives, pyrene derivatives, naphthacene derivatives, fluoranthene derivatives, triphenylene derivatives, fluorene derivatives, and chrysene derivatives; and 4) aromatic amine compounds such as triarylamine derivatives and condensed polycyclic aromatic amine derivatives.

The electron injection layer may contain a metal complex compound such as lithium (Li), ytterbium (Yb), lithium fluoride (LiF), cesium fluoride (CsF), calcium fluoride (CaF2), or 8-hydroxyquinolinolato-lithium (Liq), or a lithium oxide (LiO x) or an alkali metal, alkaline earth metal, or a compound thereof can be used.

[0279] (cathode) For the cathode, it is preferable to use a metal, alloy, electrically conductive compound, or a mixture thereof, each having a small work function (specifically, 3.8 eV or less). Specific examples of such a cathode material include elements belonging to Group 1 or 2 of the periodic table, i.e., 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), ytterbium (Yb), and alloys containing these.

[0280] In the organic EL element according to one embodiment of the present invention, the method of forming each layer is not particularly limited. Conventionally known methods such as vacuum deposition and spin coating can be used. Each layer such as the light-emitting layer can be formed by a known method such as vacuum deposition, molecular beam deposition (MBE), or a coating method such as dipping a solution dissolved in a solvent, spin coating, casting, bar coating, or roll coating.

[0281] In the organic EL device according to one embodiment of the present invention, the thickness of each layer is not particularly limited, but in order to generally suppress defects such as pinholes, keep the applied voltage low, and improve the luminous efficiency, the thickness is usually preferably in the range of several nm to 1 μm.

[0287] Example 1 <Fabrication of organic EL elements> A 25mm x 75mm x 1.1mm thick glass substrate (manufactured by Geomatic Co., Ltd.) with an ITO transparent electrode (anode) was ultrasonically cleaned in isopropyl alcohol for 5 minutes, and then UV ozone cleaned for 30 minutes. The ITO film thickness was 130nm. The cleaned glass substrate with the transparent electrode was attached to a substrate holder in a vacuum deposition apparatus, and compound HI was deposited on the surface on which the transparent electrode was formed so as to cover the transparent electrode, forming a compound HI film with a thickness of 5 nm. This HI film functions as a hole injection layer.

[0288] Following the formation of this HI film, a compound HT1 was evaporated to form an HT1 film with a thickness of 80 nm on the HI film, which served as a first hole transport layer. Following the formation of the HT1 film, a compound HT2 was evaporated to form a 10 nm-thick HT2 film on the HT1 film, which served as a second hole transport layer. On the HT2 film, BH-1 (host material) and BD-1 (dopant material) were co-deposited so that the ratio (weight ratio) of compound BD-1 was 2%, to form an emitting layer with a thickness of 25 nm.

[0289] Compound HBL was evaporated onto this light-emitting layer to form an electron transport layer with a thickness of 10 nm. Compound ET, an electron injection material, was evaporated onto this electron transport layer to form an electron injection layer with a thickness of 15 nm.
