Patent ID: 8394510

Claim:
An aromatic amine derivative represented by the following general formula (1) wherein L 1 represents a substituted or unsubstituted arylene group having 6 to 60 carbon atoms forming the aromatic ring, or a substituted or unsubstituted heteroarylene group having 5 to 60 atoms forming a ring; Ar 1 and Ar 2 each independently represents a 1-naphthyl group, a 2-naphthyl group, a 2-biphenyl group, a 3-biphenylyl group, a 4-biphenylyl group, a p-terphenyl-4-yl group, a p-terphenyl-3-yl group, a p-terphenyl-2-yl group, a m-terphenyl-4-yl group, a m-terphenyl-3-yl group or a m-terphenyl-2-yl group; R 1 represents an unsubstituted aryl group having 6 to 60 carbon atoms forming the aromatic ring; R 2 represents a hydrogen atom, an unsubstituted aryl group having 6 to 60 carbon atoms forming the aromatic ring, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 50 carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 50 atoms forming a ring, a substituted or unsubstituted arylthio group having 5 to 50 atoms forming a ring, a substituted or unsubstituted alkoxycarbonyl group having 2 to 50 carbon atoms, a halogen atom, a cyano group, a nitro group, a hydroxyl group or a carboxyl group; with the proviso that L 1 , Ar 1 , Ar 2 and R 2 do not contain a fluorene structure, and that the number of a carbazole structure in the aromatic amine derivative represented by the general formula (1) is 1.
