The present invention provides a novel aromatic amine derivative having a specific 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, wherein at least one layer in the above organic thin film layer, particularly a hole injecting layer contains the aromatic amine derivative described above in the form of a single component or a mixed component. Use of the aromatic amine derivative described above materialize an organic electroluminescence device which reduces an operating voltage and makes molecules less liable to be crystallized and which enhances a yield in producing the organic EL device and has a long lifetime.
本发明提供了一种具有特定结构的新型芳香胺衍生物以及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,特别是注孔层,以单一组分或混合组分的形式包含上述芳香胺衍生物。使用上述芳香胺衍生物可以实现一种有机电致发光器件,该器件降低了操作电压,使分子不易结晶,并提高了有机EL器件的产量和寿命。
