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

摘要

Disclosed is an 1,3,5-triazine derivative represented by general formula (1) [wherein R1, R2 and R3 independently represent a hydrogen atom or a methyl group; X represents a carbon atom or a nitrogen atom; Ar1 represents an aromatic hydrocarbon group which may be substituted; and Ar2 represents a 6-membered aromatic heterocyclic group which has one or two nitrogen atoms, may be ring-fused, and may be substituted by a C1-4 alkyl group].  Also disclosed is an organic electroluminescent element comprising the 1,3,5-triazine derivative, which has a low driving voltage and a long service life.
