✦ Synopsis

Voltammetric behavior of water-soluble endohedral metallofullerene derivatives Gd@C 82 (OH) 5 (NHCH 2 COOH) 9 (GN) and Gd@C 82 (OH) 6 (NHCH 2 CH 2 SO 3 H) 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 C 82 cage in comparison with Gd@C 82 .
