USING TRIPHENYLAMINE AS HOLE TRANSPORTING MATEIAL AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

The present invention provides tertiary aryl amine having an asymmetrical structure and an organic electroluminescent device using the same. The compound has excellent electrical and luminescent properties and high charge transporting capacity, and is useful as a charge transporting material which is suitable for red, blue, and white fluorescent and phosphorescent dopant. The synthesis of the compound is economical, and the compound has the asymmetrical structure for improving the hole transporting and electron transporting capacities. The compound has high glass transition temperature (Tg) and is thermally and electrically stable for reducing the generation of crystallization when the organic electroluminescent device is operated.
