CYCLIC AZINE DERIVATIVE AND METHOD FOR PRODUCING THE SAME, AND ORGANIC ELECTROLUMINESCENT ELEMENT CONTAINING THE SAME AS CONSTITUENT

摘要

PROBLEM TO BE SOLVED: To provide a cyclic azine derivative enabling the power consumption of an organic electroluminescent element to be made lower, and to provide an organic electroluminescent element with the cyclic azine derivative serving as an electron transfer material, having long service life.

SOLUTION: The cyclic azine derivative represented by formula (1) is produced, and to be used as a constituent of an organic electroluminescent element. In formula (1), Ar1is an aromatic hydrocarbon group optionally substituted with a 1-4C alkyl or phenyl(s); Ar21and Ar22are each phenyl or pyridyl; Y1and Y2are each a carbon atom or nitrogen atom; wherein when Y2is carbon atom, Ar21and Ar22cannot be phenyl groups at the same time.
