Bottom-contact n-channel OFETs based on spin-coated films of N,N′-1H,1H-perfluorobutyl dicyanoperylenediimide (PDI-FCN2) exhibit a saturation-regime mobility of 0.15 cm2 V−1 s−1 in vacuum and good air stability. These performances are attributed to the high crystallinity and to the edge-on orientation promoted by the thermal treatment, as showed by confocal laser microscopy.
