<p>The present invention provides a material for an organic electroluminescence device having high efficiency and a long life and an organic electroluminescence device using the same. According to the present invention, the material for an organic electroluminescence device is represented by chemical formula 1. In chemical formula 1, Ar is an aryl group having 6-30 carbon atoms, a heteroaryl group having 5-30 carbon atoms or an alkyl group having 1-15 carbon atoms; R1 to R13 are each dependently an aryl group having 6-30 carbon atoms, a heteroaryl group having 5-30 carbon atoms, an alkyl group having 1-15 carbon atoms, a halogen atom or a deuterium atom; L1 represents a single bond or a divalent linking group having 4 carbon atoms or greater; and a and b are 0-3.</p> |
