摘要

A diketopyrrolopyrrole (DPP) unit with a semi-fluorinated side chain was copolymerized with bithiophenyl (BT) to afford a novel donor-acceptor (D-A) conjugated polymer PFDPP-BT (FDPP refers to the semi-fluorinated DPP unit). The non-fluorinated polymer PDPP-BT was synthesized as the reference polymer to investigate the effect of fluorination of side chains on the morphology of thin films and charge-carrier mobility. Organic thin-film transistors based on these two polymers showed decent device performance. Interestingly, the semiconductor polymer PFDPP-BT exhibited hole mobility about 3 times higher than that of the related PDPP-BT. Atomic force microscopy (AFM) and X-ray diffraction (XRD) measurements demonstrated that the semi-fluorinated side chains had a great effect on the thin film morphology and crystallinity, which led to enhancement in device performance.
