摘要
PURPOSE: A blue light emitting material of an asymmetry arylamine structure having a meta- substituted phenyl group and an organic electroluminescent device using the same is provided to present blue color with high chromatic purity and excellent luminous efficiency by including a meta- substituted phenyl group with aromatic compound as a main chain and the third amine group. CONSTITUTION: A blue light emitting material of an asymmetry arylamine structure having a meta- substituted phenyl group has an aromatic derivative indicated as the following chemical formula 1. In the following chemical formula 1, Ar1 is a substituted or non-substituted divalence aromatic arylene or a heteroarylene group. X1 is one selected from a group consisting of halogen, an amino group, an alkyl group of an arylamine group or the carbon number 1 to 40, an alkenyl group of the carbon number 2 to 40,an alkoxy group of the carbon number 1 to 40, a substituted or non-substituted cycloalkyl group of the carbon number 3 to 40, a substituted or non-substituted heterocycloalkyl group of the carbon number 3 to 40, and a substituted or non-substituted aryl group of the carbon number 5 to 50 and substituted or non-substituted heteroaryl group of the carbon number 5 to 50.
