ELECTRILUMINESCENT POLYMER CONTAINING BENZOTHIADIAZOLE DERIVATIVES AND ORGANOELECTRILUMINESCENT DEVICE EMLOYING THE SAME

摘要

PURPOSE: An electroluminescent polymer is provided to use a derivative as a benzothiazole derivative, thereby being utilized as a green light-emitting material with improved purity and improving luminous efficiency, driving voltage, and brightness performance of an organic electroluminescent device. CONSTITUTION: An electroluminescent polymer comprises a benzothiazole derivative represented by chemical formula 1. In chemical formula 1, Ar is C5-40 aromatic group or C4-40 heteroaromatic group with a heteroatom included in an aromatic ring thereof; the aromatic ring or heteroaromatic group can be substituted by C1-12 alkyl group, alkoxy group, or amine group; W can be substituted by the same or a different substituent which is C1-12 linear, branched, or cyclic alkyl group or C6-14 aromatic group; m is 0.01-1; and n is 0-0.99.
