Patent ID: 7425654

Claim:
An aromatic triamine compound represented by the following Formula (1): wherein Ar 1 to Ar 5 each are independently a substituted or unsubstituted aryl group having 6 to 30 nuclear carbon atoms; L 1 and L 2 each are independently a linkage group having 6 to 30 nuclear carbon atoms which has one or more benzene rings, and one of L 1 and L 2 is a substituted or unsubstituted terphenylene group, wherein one of L 1 and L 2 is not a terphenylene group, and wherein the linkage group of L 1 or L 2 that is not a terphenylene group is a group represented by the following Formula (2): wherein L 3 is a hetero atom, a substituted or unsubstituted alkylene group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkylene group having 3 to 30 carbon atoms, a substituted or unsubstituted arylene group having 6 to 30 nuclear carbon atoms, wherein the substituted or unsubstituted arylene group does not comprise 6 nuclear carbon atoms, or a substituted or unsubstituted heteroarylene group having 5 to 30 nuclear carbon atoms; R 31 , and R 32 each are independently a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 30 carbon atoms or a substituted or unsubstituted aryl group having 6 to 30 nuclear carbon atoms; R 31 and R 32 described above each may be plural, and in such case, plural R 31 themselves and R 32 themselves may be combined with each other to form saturated or unsaturated rings.
