<p>The present invention relates to a compound derivative used for an organic electroluminescence device; and to an organic electroluminescence device using the derivative. More specifically, the derivative used for an organic electroluminescence device has an asymmetric amine substituent with respect to an existing diphenyltriphenylene derivative. The present invention can provides an organic electroluminescence device having a lower driving voltage and higher luminous efficiency than those of an existing organic electroluminescence device; and can introduce various amine substituents without the probability of thermal composition in a sublimation refining process. Accordingly, the present invention has an effect in which the derivative used for an organic electroluminescence device can be variously used in a hole transfer layer and also in a light emitting layer, an electron transporting layer, etc. According to the present invention, an organic electroluminescence composition comprises an aromatic amine derivative represented by chemical formula I.</p> |
