Abstract

We report on the fabrication and characterization of ambipolar organic field-effect transistors based on the solution-processable quinoidal oligothiophene [QQT(CN)4] and using a new fluorinated polymer (AL-X601) with a dielectric constant of 3.1 as dielectric material layer. As-prepared devices show ambipolar transport with hole and electron field-effect mobilities of 6 × 10-2 and 5 × 10-3 cm2/V s respectively as well as an on and off state current ratio higher than 10 3. Influence of a thermal annealing on the device performances was investigated and was found to lead to a majority carrier type conversion from a p-type to an n-type dominant behavior. QQT(CN)4 based field-effect transistors and complementary inverters fabricated on flexible substrates and using Al-X601 as gate dielectric material show high performance and good mechanical stability.
