AB  - The n-type organic semiconductor phenyl-C61-butyric acid methyl ester (PCBM), a 
      soluble fullerene derivative well investigated for organic solar cells and 
      transistors, can undergo several successive reversible, diffusion-controlled, 
      one-electron reduction processes. We exploited such processes to shed light on 
      the correlation between electron transfer properties, ionic and electronic 
      transport as well as device performance in ionic liquid (IL)-gated transistors. 
      Two ILs were considered, based on bis(trifluoromethylsulfonyl)imide [TFSI] as the 
      anion and 1-ethyl-3-methylimidazolium [EMIM] or 1-butyl-1-methylpyrrolidinium 
      [PYR14] as the cation. The aromatic structure of [EMIM] and its lower steric 
      hindrance with respect to [PYR14] favor a 3D (bulk) electrochemical doping. As 
      opposed to this, for [PYR14] the doping seems to be 2D (surface-confined). If the 
      n-doping of the PCBM is pursued beyond the first electrochemical process, the 
      transistor current vs. gate-source voltage plots in [PYR14][TFSI] feature a 
      maximum that points to the presence of finite windows of high conductivity in 
      IL-gated PCBM transistors.
