Abstract

We demonstrated the synthesis of two new solution-processed triphenylene-based semiconductors and characterized their physical, optical, and electrochemical properties. Both were intriguingly capable of producing smooth films and high-quality microcrystalline objects. The single-crystal-based field-effect transistors (FETs) using these semiconductors displayed a maximum carrier mobility of ∼0.03 cm² V^-1 s^-1 and a high on/off current ratio of ∼10³. Notably, the mobilities of the single-crystal-based FETs were measured to be two orders of magnitude greater than those of the thin-film transistors. To our knowledge, the carrier mobility obtained in this work is the highest ever reported for single-crystal FETs made of triphenylene analogues.
