High Electron Mobility and Ambient Stability in Solution-Processed Perylene-Based Organic Field-Effect Transistors
Bottom-contact n-channel OFETs basedon spin-coated films of N,N'-1H,1H-perfluorobutyl dicyanoperylenediimide (PDI-FCN2) exhibit a saturation-regime mobility of 0.15 cm(2) 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.
