Description: 
Here, electron-transporting semiconducting organic channels made of N,N′-1H, 1H-perfluorobutyl dicyanoperylenecarboxydiimmide (PDIF-CN2) molecules were thermally evaporated on flexible polyethylene-naphtalate (PEN) plastic substrates equipped with gold (Au) electrodes. This multilayer structure represents the basic component for the fabrication of staggered top-gate n-type organic thin-film transistors (OTFTs) to be completed with the addition of a polymeric dielectric layer and an aluminum gate electrode. PEN substrate was treated with hexamethyldisilazane (HMDS) in order to make it more hydrophobic. Indeed, the hydrophobized surface of the plastic substrate was shown to induce a more ordered supramolecular structure of the semiconductor layer during the evaporation process. The hybrid organic/inorganic formally trilayer non-passivated OTFT structure was successfully profiled in a single run …
