Abstract:
Novel donor-acceptor π-conjugated copolymers, P(DPP-BDT) and P(DPP-ANT), were synthesized in 87-89% yield. Thin-film transistors (TFTs) made from the thermally annealed film of P(DPP-ANT) exhibited much better performance (e.g., μmax = 1.90 cm(2) V(-1) s(-1), Ion/off ≈ 10(6)) than those made from the thermally annealed film of P(DPP-BDT).
