Provided are a novel aromatic amine derivative having a specific structure and an organic electroluminescence device in which an organic thin layer comprising a single layer or plural layers including a light emitting layer is interposed between a cathode and an anode, wherein at leas one layer of the above organic thin layer contains the aromatic amine derivative described above in the form of a single component or a mixed component. Thus, the organic electroluminescence device is less liable to be crystallized in molecules, improved in a yield in producing the organic electroluminescence device and extended in a lifetime.
提供了一种具有特定结构的新型芳香胺衍
生物和一种有机电致发光器件,其中在阴极和阳极之间夹有包括发光层的单层或多层有机薄层,上述有机薄层中的至少一层以单一成分或混合成分的形式包含上述芳香胺衍
生物。因此,该有机电致发光器件不易在分子中结晶,生产有机电致发光器件的产量和寿命得到了提高。
