Two donor–acceptor (D−A) copolymer PDVTs based on diketopyrrolopyrole and (E)-2-(2-(thiophen-2-yl)vinyl)thiophene (TVT) units are synthesized for solution-processed field-effect transistors (FETs). The highly π-extended TVT strengthen the coplanarity of polymer backbone. FETs show high mobilities above 2.0 cm2 V−1 s−1 with a current on/off ratio 105−107, shelf storage, operation stability.

Rational heteroatom engineering is applied to develop high-performance electron-transporting naphthalenediimide copolymers. Top-gate field-effect transistors fabricated from selenophene-containing polymers achieve an ultrahigh electron mobility of 8.5 cm2 V-1 s-1 and excellent air-stability. The results demonstrate that the incorporation selenophene heterocycles into can improve film-forming ability, intermolecular interaction, carrier transport significantly.
