Abstract

The synthesis of the novel donor-acceptor monomer 4,7-bis[(E)-2-(5-bromo-3-dodecylylthiophen-2-yl)ethenyl]-5,6-difluoro-2,1,3-benzothiadiazole (FBT-V2T2) is reported. Polymerization with 4,4′-ditetradecyl-5,5′-bistrimethylstannyl-2,2′-bithiophene afforded a highly crystalline polymer that aggregated strongly in solution. Polymer films were well ordered resulting in high performance field-effect transistors with low onset voltages, negligible hysteresis, high channel current on/off ratios, and peak hole mobilities of up to 0.5 cm² V^-1 s^-1. Notably the transistors exhibited close to ideal behavior with extracted mobilities almost independent of gate of voltage.
