Abstract

Novel luminescent copolymers, poly(3-(2-benzotriazoloethyl)thiophene-co-octylcarbazolylene) ([(BET)m-OcCz2]n) that contain both electron transporting benzotriazole and hole transporting octylcarbazole moiety were synthesized by oxidation of ferric chloride with changing the composition ratio of BET and OcCz. The absorption peak of UV-VIS was blue-shifted from λmax= 440 nm in poly(3-(2-benzotriazoloethyl)thi ophene) (PBET) to λmax= 412 nm in [(BET)4-OcCz2]n. The photolumine scence (PL) and electroluminescence (EL) intensities of the polymers were decreased with presence of carbazole moieties in the copolymer.
