TES anthradithiophene solution-processed OTFTs with 1 cm/sup 2//V-s mobility

We have fabricated solution processed organic thin film transistors (OTFTs) based on triethylsilylethynyl anthradithiophene (TES anthradithiophene) with 1 cm/sup 2//V-s mobility. The devices also have current on/off ratio > 107 and subthreshold slope near 1 V/decade. To our knowledge, these are the highest mobility solution-processed OTFTs reported to date and the first with performance comparable to thermally evaporated pentacene devices.
