摘要

PROBLEM TO BE SOLVED: To provide cyclic azine compounds capable of prolonging the lifetime of an organic electroluminescent element, and the organic electroluminescent element capable of being driven at low voltage and containing the same as an electron transport material.SOLUTION: There is provided cyclic azine compounds represented by the general formula (1), where Y represents C-H or a nitrogen, Arrepresents an aromatic hydrocarbon group having 6 to 18 carbon atoms which may be substituted by an alkyl group or a phenyl group, Arrepresents an aromatic hydrocarbon group having 6 to 18 carbon atoms which may be substituted by a phenyl group or a pyridyl group, or a nitrogen-containing condensed cyclic aromatic group having 9 to 15 carbon atoms, Arrepresents a nitrogen-containing condensed cyclic aromatic group having 9 to 15 carbon atoms, X represents a phenyl group and n represents an integer of 0 to 3.
