Organic electroluminescent device and preparation thereof |
摘要 |
In the organic electroluminescence (EL) device containing a bis-condensed derivative of 4-(dicyanomethylene)-2-methyl-6-(para-(dimethylaminostyryl)-4H-pyran, and the preparation thereof, the inventive organic electroluminescence device has a high luminescent efficiency and color coordinates based on a high purity, and is further simple in a synthesis and is prominent in a thermal stability, thereby providing great merits to a mass production of the organic electroluminescence device.
