Aceno[2,1,3]thiadiazoles for Field-Effect Transistors: Synthesis and Crystal Packing

An efficient synthetic approach to a series of aceno[2,1,3]thiadiazole derivatives is described. 2-TIPS and 2-TES molecules exhibited different crystal packings, and 2-TIPS show good device performances with hole mobility up to 0.4 cm2 V–1 s–1 and an average mobility of 0.15 cm2 V–1 s–1 as the active material for organic field-effect transistors. All of the results demonstrate these aceno[2,1,3]thiadiazole derivatives as promising materials for optoelectronic devices.
