Aqueous solubilization of crystalline fullerenes by supramolecular complexation with γ-cyclodextrin and sulfocalix[8]arene under mechanochemical high-speed vibration milling
Abstract
The solid-state supramolecular complexation of fullerenes C60 and C70 as well as some derivatives of C60 was attained with γ-cyclodextrin by the use of a mechanochemical high-speed vibration milling technique. Similarly C60 and the fullerene dimer C120 were complexed with sulfocalix[8]arene. The complexes produced were found to be soluble in water, and their solubility was examined by UV-vis spectroscopy.
