A new clustered fullerene material {C70}n has been prepared and studied using UV/vis spectroscopy, dynamic light scattering and liquid-liquid extraction. The material was prepared from aqueous fullerene dispersions of C70 by ultracentrifugation. The dispersions were obtained via an ordinary solvent-exchange procedure. Liquid–liquid extraction of {C70}n from water to the organic phase without any extra reagents was observed for the first time. {C70}n fullerene solid material was made and characterized with transmission electron microscopy and differential scanning calorimetry.
Keywords: fullerenes, solid material, extraction properties, DSC.
