Abstract A low‐band gap semiconducting polymer with an acceptor–donor–acceptor architecture is newly designed and synthesized by incorporating a π‐extended thiazole–vinylene–thiazole unit. The resulting thiazole‐containing diketopyrrolopyrrole copolymer exhibits well‐balanced ambipolar characteristics with hole mobility of up to 0.11 cm 2 V −1 s −1 and electron mobility of up to 0.30 cm 2 V −1 s −1 , which are suitable for applications in polymer electronics.
