Dual-gate organic thin-film transistors (OTFTs) of octathio[8]circulene (1) with ionic liquid and SiO2 gate dielectrics lead to good transistor performance with a high on/off ratio (similar to 10(5)), a low threshold voltage (similar to-5 V), a low subthreshold slope (similar to 150 mV/decade), and low power operation, thus surpassing the performance of the single-gate OTFTs of 1. This operation is a promising method for improving the carrier concentrations in OTFTs and for realizing high-performance OTFTs.
