AROMATIC AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME |
摘要 |
<p>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.</p> |
