AROMATIC AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME |
摘要 |
Disclosed is a novel aromatic amine derivative having an asymmetric structure. Also disclosed is an organic electroluminescent device wherein an organic thin film composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode. Since at least one layer of the organic thin film contains the aromatic amine derivative by itself or as a component of a mixture, molecules are hardly crystallized, thereby improving the production yield of the organic electroluminescent device. This organic electroluminescent device has a long life.
