NOVEL BLUE FLUORESCENT HOST COMPOUND AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING SAME

摘要

A blue fluorescent host compound of the present invention has excellent quantum efficiency, excellent efficiency of maintaining blue light emission and light emission, high color purity, and high efficiency, and improves durability by preventing crystallization. Therefore, when the blue fluorescent host compound is applied to an organic light emitting device, the organic light emitting device using low driving voltages has excellent efficiency of maintaining blue light emission and light emission, high color purity, and high efficiency, and improves high durability.
