Fullerene, Cyclic Voltammetry

The cyclic voltammograms of 1-cyano-2-hydroxy-1,2-dihydrofullerene derivatives indicate a complex redox behavior. The first reduction peak of these new compounds is at less nega- tive values compared to the parent [60]fullerene. This is a consequence of the two electron- withdrawing groups, which are attached directly to the C60moiety.
