文摘

A series of electron-accepting π-conjugated molecules having fluorine-containing dicyanovinylidene as terminal groups has been synthesized for the application to electron-transporting semiconductors. This terminal group can be easily incorporated into π-conjugated frameworks. Electrochemical measurements indicated that these compounds showed low-lying lowest unoccupied molecular orbital energy levels, which could be fine-tuned by the combination of central unit. The thin films fabricated by solution process showed typical electron-transporting characteristics in field-effect transistors.
