TRIPHENYLENE COMPOUND INCLUDING AROMATIC AMINE IN WHICH ELECTRON TRANSMISSION ABILITY, HOLE INJECTION/TRANSMISSION ABILITY AND/OR LUMINANCE ARE EXCELLENT AND AN ORGANIC ELECTROLUMINESCENT ELEMENT INCLUDING THE SAME

摘要

PURPOSE: A triphenylene compound is provided to improve power efficiency and luminous efficiency when using as the material for an organic electroluminescent display by high hole injection ability and hole transmission ability relative to NPB which is used as the material for hole injection and transmission.;CONSTITUTION: A triphenylene compound is in the chemical formula 1. In the chemical formula 1: A is a single bond, phenyl, naphthyl, and substituted or non-substituted heteroaryl with a 6-10 nucleus atom number; B is the substituted or non-substituted C6-C10 aryl and substituted or non-substituted heteroaryl with a 6-10 nucleus atom number; X is one selected from N, O and S; each l and m is independently 0 or 1; n is integer 1 or 2; and Ar1-Ar4 are substituted or non-substituted C6-C20 aryl, substituted or non-substituted heteroaryl with a 6-10 nucleus atom number. When X is O or S, one among l and m is 0.;COPYRIGHT KIPO 2012
