High‐performance polymer semiconductors are highly desired in organic electronics. G. Yu, Y. Q. Liu, and co‐workers develop two highly π‐extended donor–acceptor copolymers based on diketopyrrolopyrrole and (E)‐2‐(2‐(thiophen‐2‐yl) vinyl)thiophene units for applications in solutionprocessed polymer field‐effect transistors. Stable high‐performance transistors are fabricated and show an excellent hole...
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 units strengthen the coplanarity of the polymer backbone. FETs based on PDVTs show high mobilities above 2.0 cm2 V−1 s−1 with a current on/off ratio of 105−107, high shelf storage,...
