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

Pyrrolidine and N N-dimethylpyrrolidinium derivatives of C-60 could be solubilized in water with the aid of gamma 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 C-60 derivatives reported previously Furthermore these solutions are stable for at least one month at room temperature
