It was found recently that diketopyrrolopyrole (DPP)-based copolymer with donor�acceptor (D-A) structure showed high performance for field-effect transistors (FETs). For example, the hole mobility higher than 3.0 cm2V-1s-1 has been achieved with a long hexadecyl side-chains D�A copolymer. However, the polymer based FETs possessed of excellent charge-carrier transporting characteristics, good air- and operation-stability simultaneously, are still a big challenge in the development of polymeric electronics. In this presentation,1,2 we will introduce our design concept, synthesis of new copolymers, fabrication of FET devices, and investigation of their electronic properties. The devices exhibited a maximum hole mobility over 10 cm2V-1s-1, on/off ratio greater than 106, together with high stability, representing a significant progress in polymeric electronics.Huajie Chen, Yunlong Guo, Gui Yu, Yan Zhao, Ji Zhang, Dong Gao, Hongtao Liu, and Yunqi Liu, Adv.
