Аннотация: A new clustered fullerene material {C$_{70}$}$_{n}$ 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 C$_{70}$ by ultracentrifugation. The dispersions were obtained via an ordinary solvent-exchange procedure. Liquid-liquid extraction of {C$_{70}$}$_{n}$ from water to the organic phase without any extra reagents was observed for the first time. {C$_{70}$}$_{n}$ fullerene solid material was made and characterized with transmission electron microscopy and differential scanning calorimetry.

Ключевые слова: fullerenes, solid material, extraction properties, DSC.
