The position effect of an ethynyl spacer on the carrier mobility of anthracene derivatives

Abstract

Two oxidation-stable naphthalenyl ethynyl anthracene derivatives have been synthesized via Sonogashira coupling. In contrast to a 1-position substituted anthracene derivative with near zero mobility, the functionalization at the 2-position of anthracene gives rise to a densely packed structure and a uniform film with mobility up to 1.6 cm2 V−1 s−1, which is one of the highest values for thin film transistors based on anthracene derivatives.
