    • The applicability of the Hill equation to small molecule self-assembling systems has recently been under discussion. In a careful analysis, G. Ercolani (Ercolani, G. J. Am. Chem. Soc. 2003, 125, 16097-16103) has argued in favor of the use of the Hill equation only for intermolecular binding of monovalent ligands to a multivalent receptor. Our proposed binding mode fits with this case, since the binding of C60 always occurs intermolecularly

    • Although it is often considered a direct indication of the number of available binding sites on the receptor, the Hill coefficient is best thought of as an interaction coefficient reflecting the extent of cooperativity, with a maximum value equal to the number of binding sites see: Connors, K. A. Binding Constants; John Wiley & Sons: New York, 1987

    • The influence of the concentration of C60 on the cathodic shift of its reduction waves can be considered as negligible. Although this is the typical electrochemical behaviour for a reversible species (see ref 34, we have carried out the cyclic voltammograms of pristine C60 at different concentrations and no shift for the reduction waves are observed see Figure S11
