An aromatic amine derivative having a specific structure. An organic electroluminescence device which is composed of one or more organic thin film layers including at least one light emitting layer sandwiched between a cathode and an anode, wherein at least one of the organic thin film layers contains the aromatic amine derivative or a material for the organic electroluminescence device singly or as its mixture component. They provide an organic electroluminescence device with an enhanced efficiency of light emission and having prolonged lifetime emitting blue light, a novel aromatic amine derivative and a material for the organic electroluminescence device realizing the device.
具有特定结构的芳香胺衍生物。一种有机电致发光器件,由至少包括一个发光层的一个或多个有机薄膜层组成,该发光层夹在阴极和阳极之间,其中至少一个有机薄膜层包含芳香胺衍生物或有机电致发光器件的材料,单独或作为其混合成分。它们提供了一种具有增强发光效率并具有长寿命的发出蓝光的有机电致发光器件,一种新颖的芳香胺衍生物和一种实现该器件的有机电致发光器件材料。
