Donor-acceptor type polymers were generally showed low solubility and processability. To enhance solubility of polymer, units with long chains were introduced as side chains. In this study, the polymer was synthesized by Suzuki coupling reaction. According to the used solvent in polymerization, the molecular weight and absorption coefficient of copolymer were increased. The synthesized polymer was characterized structural and opto-electronical analysis by 1H-NMR, GPC, UV-visible spectroscopy and cyclic voltammogram, and the fabricated devices were measured. |
