More Information
Summary:In the organic electrolumineScenCe(EL) device containing a bis-condensed derivative of 4-(dicyanomethylene)-2-methyl-6- (para-(dimethylamineostyryl)-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, to thereby providing great merits to a mass production of the organic electroluminescence device.
