Regiochemically well-defined fluorenone-alkylthiophene copolymers: synthesis, spectroscopic characterization, and their postfunctionalization with oligoaniline
A new solution processable, regioregular, alternate copolymer of fluorenone and dialkylbithiophene, namely poly [(5, 5'-(3, 3'-di-n-octyl-2, 2'-bithiophene))-alt-(2, 7-fluoren-9- one)](abbreviated as PDOBTF), was synthesized by three different preparation methods: chemical or electrochemical oxidation of 2, 7-bis (4-octylthien-2-yl)-fluoren-9-one or polycondensation of 2, 7-bis (5-bromo-4-octylthien-2-yl)-fluoren-9-one in the presence of ...
