Synthesis and Characterization of copolymers consisting of 3-hexylthiophene and biphenyl derivatives
Two novel copolymers consisting of 3-hexylthiophene and 4,4-di(thiophen-2-yl)biphenyl (DTBHT) or 4,4-di(thiophen-2-yl)-2-nitrobiphenyl (DTNHT) were synthesized.Both of the copolymers show lower HOMO energy level (-5.62,-5.51 eV) than that of the P3HT (-5.1 eV).Compared to DTBHT,adding nitro group in DTNHT improves effective conjugation of the main chain and successfully lowers the electrochemical bandgap of the copolymers from 2.39 to 2.28 eV and optical band-gap from 2.17 to 2.07 eV with significant increase in fluorescence quantum yield from 0.140 to 0.252.
