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 cm 2 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
