ARYL AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENCE DEVICE USING THE SAME

摘要

An aryl amine derivative is provided to secure stability of materials due to the increase of glass transition temperature(Tg), and to improve stability, luminous efficiency, brightness and power efficiency of a organic electro luminescence device when used as a hole transfer material. An aryl amine derivative represented by chemical formula 1 comprises tetrahydropyrene as a core has an amine group substituent of independently -NAr^1Ar^2 and -NAr^3Ar^4 at position 2 and position 7. X^1 and X^2 between tetrahydro pyrene and amine groups (-NAr^1Ar^2 and -NAr^3Ar^4) are aromatic ring groups which is independently substituted and is not substituted. An organic electroluminescence device comprises (i) a positive electrode, (ii) a negative electrode, and (iii) at least one organic material layer between the positive electrode and negative electrode.
