A novel aromatic amine derivative having an asymmetric structure; and an organic electroluminescence device comprising a cathode, an anode and an organic thin film layer which is disposed between the cathode and the anode and comprises at least one layer comprising a light emitting layer, wherein at least one layer in the organic thin film layer comprises the above aromatic amine derivative singly or as a component of a mixture. Crystallization of the molecules is suppressed, and the yield in the production of the organic electroluminescence device can be increased.
一种具有不对称结构的新型芳香胺衍生物;以及一种有机电致发光器件,该器件包括一个阴极、一个阳极和一个有机薄膜层,该有机薄膜层设置在阴极和阳极之间,并包括至少一层发光层,其中有机薄膜层中的至少一层由上述芳香胺衍生物单独或作为混合物的组分组成。分子的结晶被抑制,有机电致发光器件的生产率可以提高。
