CYCLIC AZINE DERIVATIVES, PROCESSES FOR PRODUCING THESE, AND ORGANIC ELECTROLUMINESCENT ELEMENT CONTAINING THESE AS COMPONENT

摘要

Disclosed is a cyclic azine derivative represented by general formula (1). This cyclic azine derivative is useful as an organic-compound layer in fluorescence-type and phosphorescence-type organic electroluminescent elements. [In formula (1), Ar1 represents an aromatic group optionally substituted by a C1-4 alkyl, phenyl, or pyridyl, and A represents a group represented by any of general formulae (2) to (5) described in the description.]
