High-Performance n-Type Organic Thin-Film Transistors Based on Solution-Processable Perfluoroalkyl-Substituted C60 Derivatives

We have demonstrated n-type organic thin-film transistors (OTFTs) based on solution-processable perfluoroalkyl-substituted C60 derivatives. C60PC12F25-based OTFTs exhibit high electron mobility of 0.25 cm2/(V s) and can operate in air. We found that introduction of a long-chain perfluoroalkyl group to C60 is effective for fabrication of stable and high performance n-type OTFTs.
