<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, Ar1 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; Ar2 is a condensed ring having 6-30 carbon atoms or a condensed ring having a carbon atom and a nitrogen atom; Ar1 and Ar2 are different substituents; R1 to R17 are 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; a and b are an integer of 0-3; and L1 and L2 are a single-bond divalent linking group having 4 carbon atoms or greater.</p> |
