Stable colloidal suspensions of fullerene C60 and C70 in water are readily accessible by mechanical grinding a mixture of fullerene and p-sulfonatocalixarene and/or imidazolium zwitterion followed by ultrasonication on the addition of water. The yellow and brown solutions for C60 and C70 respectively contain nano-arrays of fullerenes (40 to 130 nm in diameter) covered by a sheath of sulfonated calixarene, sulfonated imidazolium zwitterions or supermolecules of these two moieties.
