Provided are a novel aromatic amine derivative having an asymmetric structure and an organic electroluminescence device in which, an organic thin film layer comprising a single layer or plural layers including at least a light emitting layer is interposed between a cathode and an anode, at least one layer in the above organic thin film layer contains the aromatic amine derivative described above in the form of a single component or a mixed component, whereby molecules are less liable to be crystallized; a yield in producing the organic electroluminescence device is enhanced; and a lifetime is extended.
提供了一种具有不对称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至少一个发光层的单层或多层有机薄膜层,上述有机薄膜层中的至少一层以单一组分或混合组分的形式含有上述芳香胺衍
