摘要：

We report a first investigation of two new isomer-pure thieno[f, f'] bis[1] benzothiophenes, i.e. syn and anti with respect to the orientation of the thiophenes along the long axis of the molecule, applied as organic semiconductors in organic field-effect transistors. The field-effect mobility of both regioisomers is substantial and reaches up to 0.12 cm(2) V-1 s(-1), a value that is at most one order of magnitude lower than the best known organic transistors based on silicon dioxide gate insulators.
