NOVEL ASYMMETRIC ARYLAMINE DERIVATIVES FOR ORGANIC ELECTROLUMINESCENT ELEMENT, MANUFACTURING METHOD OF THE SAME, ORGANIC THIN LAYER MATERIAL AND THE ORGANIC ELECTROLUMINESCENT ELEMENT EMPLOYING THE SAME

摘要

PURPOSE: A symmetric arylamine derivative for organic electroluminescent element is provided to improve luminous efficiency and lifetime property by including aryl group which has electron transporting ability. CONSTITUTION: A symmetric arylamine derivative, which does not have a symmetric plane or a symmetric axis in molecule structure by introducing secondary amine and tertiary amine as a substituent, is in the chemical formula 1. In the chemical formula 1, Ar is C10-20 divalent aryl group, and Ar1 is C2-90 aryl group including a divalent pentagon ring. Each Ar2-Ar5 is same or different, and is C6-30 aryl group. But when the location of the secondary amine and the tertiary amine is symmetric, at least one among Ar2-Ar5 has different structure.
