An unsymmetrical pentacene derivative with ambipolar behavior in organic thin-film transistors

Abstract

Three new unsymmetrical anthracenyl-pentacene derivatives have been synthesized, characterized using X-ray crystallography, and used as semiconductors in OTFTs. For one derivative, ambipolar charge carrier transport was observed with a hole mobility of 0.2 cm2 V−1 s−1 and an electron mobility of 0.03 cm2 V−1 s−1. © 2013 The Royal Society of Chemistry.
