Patent ID: 7705183

Claim:
An aromatic amine derivative represented by the following general formula (I): wherein X represents a substituted or unsubstituted fused polycyclic hydrocarbon group having 10 to 50 ring carbon atoms; A 1 to A 4 each independently represents a substituted or unsubstituted aryl group having 5 to 50 ring carbon atoms, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, wherein the alkyl group is selected from the group consisting of an ethyl group, a propyl group, an isopropyl group, a butyl group, a sec-butyl group, a tert-butyl group, a pentyl group, a hexyl group, a heptyl group, an octyl group, a stearyl group, a trichloromethyl group and a trifluoromethyl group, a substituted or unsubstituted cycloalkyl group having 3 to 50 ring carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 50 ring carbon atoms or a substituted or unsubstituted heterocyclic group having 5 to 50 ring carbon atoms; R 1 represents a substituted or unsubstituted silyl group having 3 to 20 carbon atoms, wherein the substituted silyl group is selected from the group consisting of a trimethylsilyl group, a triethylsilyl group, a t-butyldimethylsilyl group, a vinyldimethylsilyl group, a propyldimethylsilyl group, a triphenylsilyl group, a dimethylphenylsilyl group and a diethylmethylsilyl group; R 2 is selected from the group consisting of: a hydrogen atom; a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, wherein the substituted alkyl group is selected from the group consisting of a methyl group, an ethyl group, a propyl group, an isopropyl group, a butyl group, a sec-butyl group, a tert-butyl group, a pentyl group, a hexyl group, a heptyl group, an octyl group, a stearyl group, a trichloromethyl group, and a trifluoromethyl group; a substituted or unsubstituted aryl group having 5 to 50 ring carbon atoms; a substituted or unsubstituted aralkyl group having 6 to 50 ring carbon atoms; a substituted or unsubstituted cycloalkyl group having 3 to 50 ring carbon atoms; a substituted or unsubstituted alkoxyl group having 1 to 50 carbon atoms; a substituted or unsubstituted aryloxy group having 5 to 50 ring carbon atoms; a substituted or unsubstituted arylamino group having 5 to 50 ring carbon atoms; a substituted or unsubstituted alkylamino group having 1 to 20 carbon atoms; and a substituted or unsubstituted heterocyclic group having 5 to 50 ring carbon atoms; a represents an integer of 1 to 3, b represents an integer of 1 to 2, c represents an integer of 0 to 4, and when a, b or c is 2 or greater, a plural of —NA 3 A 4 may be the same as or different from each other, a plural of R 1 may be the same as or different from each other, and a plural of R 2 may be the same as or different from each other, respectively.
