ASYMMETRICAL ARYL AMINE DERIVATIVE FOR ORGANIC ELECTROLUMINESCENCE DEVICES, METHOD FOR PREPARING SAME, ORGANIC THIN FILM FOR ORGANIC ELECTROLUMINESCENCE DEVICES AND ORGANIC ELECTROLUMINESCENCE DEVICE USING SAME

摘要

The present invention relates to an asymmetrical aryl amine derivative for organic electroluminescence devices, wherein different secondary and tertiary amines are sequentially introduced into the backbone of the aryl Ar compound which does not have a symmetrical axis in its molecular structure, a method for its preparation, an organic thin film material for said devices and an organic electroluminescence device using the same. The asymmetrical aryl amine derivative according to the present invention with different substituents introduced into the aryl Ar backbone of its central structure are used for making organic thin film for organic electroluminescence devices and exhibits superior luminescence efficiencies and excellent lifetime characteristics in the blue wavelength region when used as a luminescent layer material, in particular, as a dopant material in the fabrication of organic electroluminescence devices.
