| Abstract: | Voltammetric behavior of water‐soluble endohedral metallofullerene derivatives Gd@C82(OH)5(NHCH2COOH)9 (GN) and Gd@C82(OH)6(NHCH2CH2SO3H)8 (GS) was characterized in 0.1 M KCl solution by CV and DPV. They showed similar redox behavior, that is, a reversible electroreduction process on HMDE was found; in the mean time, an irreversible oxidation process and an irreversible reduction process on GC electrodes were also observed. The results reveal that these two water‐soluble endohedral metallofullerene derivatives have good electron donating ability and poor electron accepting ability due to hydroxy groups, aminoacetic acid and aminoethyl sulfonic acid connected to the C82 cage in comparison with Gd@C82. |
