POLYMER COMPOUND WITH EXCELLENT HOLE TRANSPORT ABILITY IN WHICH AN ARYLAMINE GROUP IS INCLUDED IN PHENOXAZINE AND AN ORGANIC LIGHT EMITTING DEVICE CONTAINING THE POLYMER

摘要

PURPOSE: A polymer compound is provided to enhance hole mobility as aryl amines are introduced to both sides of a phenoxazine monomer and to improve the efficiency and lifetime of an organic light-emitting device since a hole transporting layer material is excellent.;CONSTITUTION: A polymer is represented by chemical formula 1. In chemical formula 1, n is a real number of 0.01-0.99; X is O or S; R1 is H, or C1-20 linear alkyl group, C1-20 branched alkyl group, C3-20 cyclic alkyl group, or C6-14 aromatic group; R2 and R3 are a C6-26 aromatic group or a heteroaromatic group in which heteroatoms are substituted; and Ar is a C1-20 linear alkyl group, C1-20 branched alkyl group, C6-26 aromatic group or hetero-aromatic group in which heteroatoms are substituted.;COPYRIGHT KIPO 2012
