Abstract :
The synthesis of two α,α′-disubstituted bis(dithienothiophene) (BDT) derivatives is described. These have been deposited by vacuum sublimation as the active layers in organic thin film transistors (TFTs). The devices exhibit high ON/OFF ratios and preliminary studies show mobilities of 1 X 10−3 and 2 x 10−2 cm2 V−1 s−1 respectively for dithiohexyl (DTH-BDT) and dioctyl (DO-BDT) substituted bis(dithienothiophene). DTH-BDT is found to be considerably more soluble than the unsubstituted BDT.
