More Information
Summary:The present invention relates to an organic electroluminescent (EL) device and a preparation thereof; and, more particularly, to an organic EL device and a preparation thereof, in which a new bis-condensed DCM (4-(dicyanomethylene)-2-methyl-6-(para-(dimethylaminostyryl)-4H-pyran) derivative is used as an electroluminescence material. 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.
