摘要

The synthesis of the novel donor acceptor monomer 4,7-bis[(E)-2-(5-bromo-3-dodecylylthiophen-2-yOethenyl]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 cm(2) V-1 s(-1). Notably the transistors exhibited close to ideal behavior with extracted mobilities almost independent of gate of voltage.
