Conjugated polymers composed of thiophene derivative donor and aromatic acceptors such as phenyl, biphenyl and fluorenyl were prepared by Suzuki-Miyaura cross-coupling reaction. The color of these polymers indicates yellow in the reduced state whereas transparent blue for the polymer using phenyl acceptor P1, black for one using biphenyl P2 and dark green for one using fluorenyl P3 in the oxidized state.
