High Electron Mobility in Air for N,N′-1H,1H-Perfluorobutyldicyanoperylene Carboxydi-imide Solution-Crystallized Thin-Film Transistors on Hydrophobic Surfaces

High-mobility and air-stable n-type organic field transistors based on solution-crystallized N,N'-1H,1H-perfluorobutyldicyanoperylenecarboxydi-imide (PDIFCN2) are developed. Electron mobility as high as 1.3 cm(2) V-1 s(-1) is achieved owing to the almost-perfect periodic crystal packing.
