Abstract

We report a joint experimental and theoretical study on the electronic structure and the solid-state organisation of bis(naphthoquinone)-tetrathiafulvalene (BNQ-TTF) as a promising ambipolar semiconductor. Accordingly, organic field-effect transistors (OFETs) fabricated with this material show both hole and electron transport for the first time in TTF derivatives.
