© 2018 Elsevier B.V. Two narrow-band gap of donor-acceptor based conjugated polymers, BTTP and BTTP-CN were synthesized by Wittig copolymerization with thiophene or cyano-vinylene thiophene as the donor and 2,1,3-benzothiadiazole as acceptor units. The polymers were investigated by FT-IR, UV-V is, f...
