Indenotriphenylene-based amine derivative for organic electroluminescent device

A indenotriphenylene-based amine derivative represented by the following formula(I):

• wherein A ring represents a phenyl group and fused ring hydrocarbon units with two to four rings group, L represents a single bond or a substituted or unsubstituted divalent arylene group having 6 to 30 ring carbon atoms, p represents an integer of 0 to 7, X represents a divalent bridge selected from the atom or group consisting from O, S, C(R5)(R6) and NR7 or represents non-bridge and to form as a substituted or unsubstituted biphenyl group;
• Ar is selected from the group consisting of a substituted or unsubstituted aryl group having 6 to 50 carbon atoms, a substituted or unsubstituted heteroaryl group having 3 to 50 carbon atoms, R1 to R7 independently selected from the group consisting of a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 30 carbon atoms and a substituted or unsubstituted heteroaryl group having 3 to 30 carbon atoms.
