- Abstract
- We report the synthesis of polythiophene derivatives that contain thienyl side chains, using synthetic strategies that achieve high organic semiconductor field effect mobilities by enhancing the π-conjugation in the side chain conjugated system. With increased charge densities, we obtained high field effect mobilities, up to 0.050 cm2/Vs and 0.003 cm2/Vs from poly(3,3‴-didecylated-thiophenyl sexithiophene) (PDTST) and poly(3,3‴-didecylated-thiophenyl quaterthiophene) (PDTQT), respectively.
