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 cm(2) V(-1) s(-1) and an electron mobility of 0.03 cm(2) V(-1) s(-1).
