The synthesis of anthradithiophene-based liquid crystals and their applications in organic thin film transistors†
Abstract
In this communication, we report the development of high mobility organic thin film transistor (OTFT) devices using anthradithiophene-based organic semiconductors. Asymmetric molecular structures are introduced by attaching phenyl groups to the fused rings to obtain a wider temperature range of the liquid crystal phases of the anthradithiophene-based molecules. The rotation of the phenyl groups makes the molecules more flexible, leading to a lower liquid crystal transition temperature and a wider liquid crystal temperature range. An excellent OTFT carrier mobility of 0.68 cm2 Vā1 sā1 of the devices is achieved, which is good enough for use in the manufacturing processes of current electronic devices such as TFT liquid crystal display (LCD) devices.
