Abstract

The synthesis of sexithiophenes bearing amide or ester groups in the α,ω-terminal positions is described, along with their characterization in the solid state. The influence of the functional group on mobilities and on/off ratios of the organic FET devices was investigated. The oligomer bearing the ester functional group separated from the sexithiophene core by an ethylene spacer showed a hole field-effect mobility as high as 0.012 cm2V-1s-1, which is among the highest reported so far for organic FETs using sexithiophenes modified with polar groups. © The Royal Society of Chemistry 2006.
