<p><P>PROBLEM TO BE SOLVED: To provide a cyclic azine derivative that is used as an electron transport material in an organic electroluminescent element so as to reduce a drive voltage and simultaneously to have high heat resistance. <P>SOLUTION: The cyclic azine derivative is represented by formula (1) (wherein Ar<SP>1</SP>is an aromatic hydrocarbon which may be substituted; Ar<SP>2</SP>is phenyl, pyridyl or pyrimidyl; Ar<SP>3</SP>is an aromatic hydrocarbon composed of two to four rings which may be substituted; Z is a carbon atom or nitrogen atom; X is an phenylene or pyridylene; p is integer of 0-2: when p is 2, Xs may be the same or different). The organic electroluminescent element comprises the same as a constituent component. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
