Abstract

A facile method was developed to synthesize pentacene derivative 6,13-dichloropentacene (DCP) in high yield. The absorption spectra and electrochemistry results showed that the introduction of chlorine substituents lowered the HOMO energy level and increased the environmental stability of the compound. Single crystal diffraction revealed that DCP adopted slipped face-to-face packing mode. π–π and C–H⋯Cl interactions were observed in the crystals. The thin film transistor characteristics showed that DCP exhibited high mobility (0.20 cm2 V−1 s−1), low threshold voltage (∼−2.0 V) and good stability.
