CYCLIC AZINE COMPOUND, METHOD FOR PRODUCING THE SAME, AND ORGANIC ELECTROLUMINESCENT ELEMENT CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cyclic azine compound which allows an organic electroluminescent element to be driven for a long time, and to provide an organic electroluminescent element using the cyclic azine compound as an electron transport material.SOLUTION: The cyclic azine compound is represented by formula (1) (Cz represents an (n+1)-valent carbazole group or the like; Arand Areach represent an aromatic hydrocarbon group; Arrepresents an arylene group; Arrepresents a nitrogen-containing heteroaryl or the like; Y and Z each represent a nitrogen atom or CH; and n represents an integer of 1 or more) (Arrepresents an aryl group; Arrepresents a nitrogen-containing heteroaryl group; and m represents an integer of 1 or more).
