FLUORENE-CARBAZOLE COMPOOUND FOR HOLE TRANSFER LAYER AND ORGANIC ELECTRONIC DEVICE COMPRISING THE SAME

摘要

The present invention relates to a fluorene-carbazole compound for hole transfer layer and an organic electroluminescence device comprising the same. The compound of the present invention has high thermal stability in comparison to the conventional materials, and is easy to be formed into powder during sublimation and purification. Also, the fluorene-carbazole compound can alleviate the problem of mask getting stuck caused by flocculation, and can substantially improve operating voltage, luminance efficiency, and lifespan characteristics of an organic electroluminescence device when used as a material constituting the hole injection layer or hole transfer layer of the organic electroluminescence device. The fluorene-carbazole compound of the present invention is represented by chemical formula 1.
