Abstract
Two acceptor-acceptor (A-A) type copolymers (PIIG-BT and PIIGTPD) with backbones composed exclusively of electron-deficient units are designed and synthesized. Both copolymers show unipolar n-type operations. In particular, PIIG-BT shows electron mobility of up to 0.22 cm2 V1 s1. This is a record value for n-type copolymers based on lactam cores.
