π-Extended Thiazole-Containing Polymer Semiconductor for Balanced Charge-Carrier Mobilities

A low-band gap semiconducting polymer with an acceptor-donor-acceptor architecture is newly designed and synthesized by incorporating a pi-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.

Automated summary

The newly designed low-band gap semiconducting polymer with an acceptor-donor-acceptor architecture demonstrates well-balanced ambipolar characteristics with high hole and electron mobility, making it suitable for polymer electronics applications.
