1,3,5-TRIAZINE DERIVATIVE, PROCESS FOR PRODUCING SAME, AND ORGANIC ELECTROLUMINESCENT ELEMENT COMPRISING SAME

摘要

A 1,3,5-triazine derivative represented by formula (1):
wherein R 1 is hydrogen, C 1-4 alkyl group or substituted or unsubstituted phenyl group; n is an integer of 1-3, Ar is a substituted or unsubstituted aromatic hydrocarbon group, provided that Ar is different from two substituted quarterarylenyl groups bonded to the 1, 3 , 5-triazine ring; and V and Y are nitrogen or carbon, provided that a case where both of V and Y are carbon atoms is excluded. The organic electroluminescent device comprising the 1,3,5-triazine derivative as an electron transport material has a long lifetime.
