Abstract

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 mobility, above 8.0 cm2 V−1 s−1. The work on page 4618 demonstrates that polymer semiconductors are promising for application in flexible and low-cost organic circuits and displays
