Easily solution-processed, high-performance microribbon transistors based on a 2D condensed benzothiophene derivative
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.
