It has been recognized that the introduction of electron-withdrawing groups into π-conjugated systems increases their n-type semiconducting character. We have designed and synthesized strongly electronegative heteroaromatic units, such as difluorodioxacyclopentathiophene, bis(dicyanomethylene)difluorocyclopentathiophene, and carbonyl-bridged bithiazole, and their based π-conjugated oligomers. Solubilizing units were further introduced to the oligomers for solution-processing applications. Some of their spin-coated thin films revealed high field-effect electron mobilities as well as air-stable n-channel FET operations.
