Definitions
- the present disclosure relates to an organic electroluminescent compound, an organic electroluminescent material and an organic electroluminescent device comprising the same.
- an electroluminescent device is a self-light-emitting display device which has advantages in that it provides a wider viewing angle, a greater contrast ratio, and a faster response time.
- the first organic EL device was developed by Eastman Kodak in 1987, by using small aromatic diamine molecules and aluminum complexes as materials for forming a light-emitting layer [Appl. Phys. Lett. 51, 913, 1987].
- Iridium(III) complexes have been widely known as phosphorescent light-emitting materials, including bis(2-(2’-benzothienyl)-pyridinato-N,C-3’)iridium(acetylacetonate) [(acac)Ir(btp) 2 ], tris(2-phenylpyridine)iridium [Ir(ppy) 3 ] and bis(4,6-difluorophenylpyridinato-N,C2)picolinato iridium (Firpic) as red-, green- and blue-emitting materials, respectively.
- CBP 4,4’-N,N’-dicarbazol-biphenyl
- BCP bathocuproine
- BAlq aluminum(III) bis(2-methyl-8-quinolinate)(4-phenylphenolate)
- Korean Patent No. 1313730 discloses an organic electroluminescent device using a substituted indolocarbazole compound as a host material.
- Korean Patent No. 1529164 discloses an organic electroluminescent device using a compound, in which a pyridine, pyrimidine or triazine substituted with phenyls is linked to a benzoindolocarbazole via two consecutive naphthylenes as a linker, or a pyridine, pyrimidine or triazine substituted with phenyls is linked to an indolocarbazole via a naphthylene as a linker, only as a phosphorescent green host material.
- Korean Patent Application Laid-Open No. 2015-0077513 discloses a compound in which an indolocarbazole derivative is linked to a quinazoline or a quinoxaline via an arylene as a linker.
- the object of the present disclosure is firstly, to provide an organic electroluminescent compound capable of improving lifespan properties of an organic electroluminescent device, secondly, to provide an organic electroluminescent material comprising the organic electroluminescent compound, and thirdly, to provide an organic electroluminescent device having improved lifespan properties, comprising the organic electroluminescent compound.
- X 1 and X 2 each independently, represent N or CH, with the proviso, at least one of X 1 and X 2 represents N,
- La represents a substituted or unsubstituted divalent (C10-C30) aromatic ring, which is one condensed ring,
- a ring and C ring each independently, represent a substituted or unsubstituted benzene ring, or a substituted or unsubstituted naphthalene ring, with the proviso, at least one of A ring and C ring represents a substituted or unsubstituted naphthalene ring,
- B ring represents a substituted or unsubstituted benzene ring
- Ar 1 , Ar 2 and Ar 3 each independently, represent hydrogen, deuterium, a halogen, a cyano, a substituted or unsubstituted (C1-C30)alkyl, a substituted or unsubstituted (C6-C30)aryl, a substituted or unsubstituted (3- to 30-membered)heteroaryl, a substituted or unsubstituted (C3-C30)cycloalkyl, a substituted or unsubstituted (C1-C30)alkoxy, a substituted or unsubstituted tri(C1-C30)alkylsilyl, a substituted or unsubstituted di(C1-C30)alkyl(C6-C30)arylsilyl, a substituted or unsubstituted (C1-C30)alkyldi(C6-C30)arylsilyl, a substituted or unsubstituted
- the heteroaryl contains at least one heteroatom selected from B, N, O, S, Si, and P.
- organic electroluminescent compound of the present disclosure By using the organic electroluminescent compound of the present disclosure, it is possible to provide an organic electroluminescent device having long driving lifespan.
- an organic electroluminescent compound in the present disclosure means a compound that may be used in an organic electroluminescent device, and may be comprised in any layers constituting an organic electroluminescent device, if necessary.
