    摘要： A material for an organic electroluminescent device having high emission efficiency and an organic electroluminescent device utilizing the same. The material is represented by Formula 1. In Formula 1, X1 to X7 are each independently hydrogen, deuterium, a halogen atom, an alkyl group having 1 to 15 carbon atoms, or a substituted or unsubstituted aryl group; Ar1 and Ar2 are each independently a substituted or unsubstituted aryl group having 6 to 12 carbon atoms for forming a ring; L is a substituted or unsubstituted arylene group; n is an integer from 1 to 3; at least one L is a phenylene group represented by Formula 2. In Formula 2, Y1 to Y6 are each independently a direct linkage, hydrogen, deuterium, halogen, an alkyl group having 1 to 15 carbon atoms, an alkenyl group having 2 to 15 carbon atoms, or a substituted or unsubstituted aryl group.
