Charqe-transfer reactions between C60 and hydrophilic solutes

Abstract

Two different procedures for dissolving fullerene molecule C60 into aqueous solutions have been developed. Embedding C60 clusters into a water-soluble host molecule of λ-cyclodextrin resulted in relatively low concentration of C60 (5-10 μM). Prepare of a stable ionic surfactant/water/oil microemulsion provided a method for dissolving C60 in relatively high concentrations (1 mM) In both cases charge-transfer reactions between hydrophobic molecule of C60 and hydrophilic solutes were examined. Anion radical C60- was detected in reaction with radiolytically produced radicals (eaq-, (CH3)2ĊOH or MV+), and in reaction with excess electrons stored onto nanometer-sized metal (Ag) or quantized semiconductor (TiO2) particles.
