Quinoline or quinoxaline-fused pyrrole-carbazole derivatives as organic electroluminescence compounds and a preparation method thereof

The present invention relates to a quinoline- or quinoxaline-fused pyrrole-carbazole derivative as an organic electroluminescent compound and a preparation method thereof. An organic electroluminescent device having a low operating voltage and excellent luminance efficiency such as current efficiency and electrical power efficiency in addition to high-purity color and improved operating lifespan, can be provided by using the organic electroluminescent compound manufactured according to the present invention. The preparation method of the quinoline- or quinoxaline-fused pyrrole-carbazole derivative comprises the steps of: making a reaction between a compound represented by chemical formula 3 and a compound represented by chemical formula 4 in presence of a base, a solvent and a metallic catalyst, and preparing a compound represented by chemical formula 2; and making a reaction between the compound represented by chemical formula 2 and a ligand, a base, and a solvent in presence of a metallic catalyst, and preparing a compound represented by chemical formula 1.COPYRIGHT KIPO 2016
