摘要：
The paper presents a new strategy for the preparation of porphyrin-functionalized head-to-tail regioregular thiophene copolymers using a simple and effective post polymerization functionalization (PPF) procedure based on the synthesis of a regioregular and soluble polythiophene precursor followed by subsequent reaction with a suitably functionalized porphyrin derivative. Thus, thiophene copolymers poly[3-(6-bromohexyl)thiophene-co-(3-[5-(4-phenoxy)-10,15,20-triphenylporphyrinyl] hexylthiophene)]s at different porphyrin chromophore contents were prepared, obtaining, in all cases, very soluble and easily filmable derivatives. Their thermal, optical and electrochemical properties were determined and their performances as the active layer in bulk heterojunction solar cells tested. (C) 2014 Elsevier B.V. All rights reserved.
