Abstract

A carbazole compound represented by the following formula:

wherein, when m=1, n=0, Ar 1 , Ar 2 , Ar 3 and X 2 are C 6-50 aryl or C 4-50 heteroaryl, provided that Ar 1 and Ar 2 , or Ar 3 and X 2 may form together a ring; X 1 =C 6-50 arylene; R 1 , R 2 , R 4 , R 5 and R 7 are H, halogen, amino, C 1-18 alkyl, C 1-18 alkoxy, C 6-50 aryl or C 4-50 heteroaryl, R 3 and R 6 are H, halogen, C 1-18 alkyl, C 1-18 alkoxy, C 6-50 aryl or C 4-50 heteroaryl;
when m=0, n=1-3, Ar 3 , Ar 4 and Ar 5 are C 6-50 aryl or C 4-50 heteroaryl, Ar 4 and Ar 5 may form together a ring; X 1 =C 1-18 alkyl, C 6-50 aryl or C 4-50 heteroaryl; X 2 =C 6-50 arylene; R 1 -R 7 are H, halogen, C 1-18 alkyl, C 1-18 alkoxy, C 6-50 aryl or C 4-50 heteroaryl;
when m=0, n=0, X 1 =C 1-18 alkyl, C 6-50 aryl or C 4-50 heteroaryl; Ar 3 and X 2 are C 6-50 aryl or C 4-50 heteroaryl; R 2 =H, halogen, C 1-18 alkyl, C 1-18 alkoxy; R 1 and R 3 -R 7 are H, halogen, C 1-18 alkyl, C 1-18 alkoxy, C 6-50 aryl or C 4-50 heteroaryl. The carbazole compound is suitable for an organic EL device.

First claim

The invention claimed is:

1. A carbazole compound represented by the following general formula (12):

wherein:
Ar 15 and Ar 16 in the formula (12) independently represent a methyl-substituted or unsubstituted 4-biphenylyl group, a methyl-substituted or unsubstituted 3-biphenylyl group, a methyl-substituted or unsubstituted m-terphenylyl group, or a methyl-substituted or unsubstituted 2-fluorenyl group;
R 35 represents a straight-chain, branched or cyclic alkyl group having 1 to 18 carbon atoms, a substituted or unsubstituted biphenylyl group, a substituted or unsubstituted terphenylyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted phenanthryl group, a substituted or unsubstituted anthryl group, a substituted or unsubstituted fluoranthenyl group, a substituted or unsubstituted perylenyl group, a substituted or unsubstituted pyrenyl group, a substituted or unsubstituted pycenyl group, a substituted or unsubstituted chrysenyl group, or a substituted or unsubstituted heteroaryl group having 4 to 50 carbon atoms;
R 37 represents a hydrogen atom, a halogen atom, a straight-chain, branched or cyclic alkyl group having 1 to 18 carbon atoms, or a straight-chain, branched or cyclic alkoxy group having 1 to 18 carbon atoms; and
R 36 and R 38 through R 42 independently represent a hydrogen atom, a halogen atom, a straight-chain, branched or cyclic alkyl group having 1 to 18 carbon atoms, a straight-chain, branched or cyclic alkoxy group having 1 to 18 carbon atoms, a substituted or unsubstituted aryl group having 6 to 50 carbon atoms, or a substituted or unsubstituted heteroaryl group having 4 to 50 carbon atoms.
