Star-shaped oligothiophenes are promising materials for applications in the organic electronics field. For the first time, a range of star-oligothiophenes was oxidized to the corresponding all-S,S-dioxides by using the HOF·CH3CN complex. These materials exhibit considerable thermal stability and red-shift absorptions in the UV/vis relative to the parent compounds.
A 2D condensed benzothiophene derivative TBTDBT was synthesized. The thermal, optical and electrochemical properties were investigated. The single crystalline microribbons were grown by solution drop-casting and physical vapor transport methods respectively. The field effect transistors based on TBTDBT microribbons were fabricated and a mobility up to 2.62 cm2 V−1 s−1 and an on–off ratio greater than 105 could be achieved.
