Abstract

Hydroxylated fullerenes Gd@C82(OH)X (x ~ 20) with Gd atoms inside carbon cages have been studied by small-angle neutron scattering in light water by the variation of pH = 4-7 via salts’ addition in order to understand the characters of structural transitions and the ways of fullerenols’ supramolecular structures control and regulation. As it was found, the globular (droplet-like, diameter ~ 50 nm) clusters of fullerenols in pure water (pH = 4-5) become instable when the salts introduced into solutions (pH = 7) cause the formation of fullerenols’ chain-like aggregates (correlation radius ~ 20 nm) the structure of which is dependent on the type of salt..
