Water-soluble Inclusion Complexes of [60]Fullerene Derivatives Using γ-Cyclodextrin

Abstract

Abstract Pyrrolidine and N,N-dimethylpyrrolidinium derivatives of C60 could be solubilized in water with the aid of γ-cyclodextrin. The complexes were found to be soluble in water at high concentrations over 1.5 mM. These solubility values are significantly higher than those of other C60 derivatives reported previously. Furthermore, these solutions are stable for at least one month at room temperature.
