摘要：
The organic EL material is represented by Formula (1): where X1 to X4 are each independently a nitrogen (N) atom or a carbon atom that is monovalently bonded to R1(C—R1), R1 is a hydrogen atom, a halogen atom, an aryl group having 6 to 18 carbon atoms, a hetero aryl group having 6 to 18 carbon atoms, or an alkyl group having 1-12 carbon atoms, R2 to R10 are each independently hydrogen, an aryl group having 6 to 30 carbon atoms, or hetero aryl group having 6 to 30 carbon atoms, and at least one of X1 to X4 is a nitrogen atom.
