Synthesis, properties, and ambipolar organic field-effect transistor performances of symmetrically cyanated pentacene and naphthacene as air-stable acene derivatives

5,12-Dicyanonaphthacene and 6,13-dicyanopentacene have been synthesized for the first time. The LUMO and HOMO levels are deepened as predicted and fabricated organic field-effect transistors (OFETs) showed ambipolar responses with carrier mobilities of 10-3 cm2/V?s.
