NOVEL AMINE COMPOUND FOR ORGANIC ELECTROLUMINESCENCE MATERIAL, WHICH HAS EXCELLENT HEAT RESISTANCE DUE TO HIGH GLASS TRANSITION TEMPERATURE AND PREPARATION METHOD THEREOF

摘要

PURPOSE: Provided is an amine compound, which has excellent heat resistance and light-emitting luminance and efficiency suitable to be used as an organic electroluminescence material, has high solubility in organic solvents, and is prepared with ease. CONSTITUTION: The amine compound useful as an organic electroluminescence material is represented by the following formula 1. The amine compound of formula 1 is prepared by the method comprising a one-step coupling reaction in which 9-halophenanthrene represented by the following formula 3 as a starting material is reacted with N,N'-diphenylbenzidine, a palladium catalyst, a phosphine catalyst and a base. In formula 3, X represents a halogen atom.
