“…Fullerenols with a degree of hydroxylation n < 15 are insoluble in water but can be used for subsequent chemical modification. Fullerenols with a degree of hydroxylation of 15 < n < 29 belong to the ones with limited solubility. , The ratio of products differing in the number of hydroxyl groups and the ratio of isomers in the mixture depend on the physical–chemical conditions of hydroxylation. − The number of isomers of the highly hydroxylated complex is very large; for example, it is 5.08 × 10 19 for Gd@C 82 (OH) 22 . Therefore, it is necessary to define the most attractive structures for theoretical research.…”

The properties of the complexes I–@C60(OH)20 and I–@C60(OH)30 have been determined using the quantum chemical DFT PBE0 method to assess the possibility of synthesis of highly hydroxylated fullerene endo-iodides for the use in radiotherapy of different organs. The arrangement of the hydroxyl groups corresponds to the location of halogen atoms in (D 5d)-C60F20 and (D 3d)-C60Cl30. Negative-charged iodine is localized in the center of the fullerene cavity and has no significant influence on the IR spectra of hydroxylated fullerenes. The exothermic effect of iodide anion encapsulation in C60(OH) n (0.33 eV at n = 20; 0.03 eV at n = 30) is smaller than in C60 (0.78 eV). The energies of the lower excited singlet states computed by the TD DFT method for I–@C60(OH) n (2.11 eV at n = 20; 1.77 eV at n = 30) are larger than those for I–@C60 (1.36 eV). They indicate a low reactivity, making it possible to synthesize such complexes for medical use.

“…Today, the most common methods for obtaining aqueous liquid systems of fullerenes are as follows: the modification of the fullerene surface with functional groups such as hydroxyl and carboxyl ones [14][15][16], solvent-exchange method (with organic solvents being used at the first stage) [17,18], surface solubilization with surfactants or polymers [19,20], and even a direct dispersion of fullerenes in water [21]. However, if the surface of fullerenes does not undergo a strong modification, none of those techniques makes it possible to produce liquid systems with fullerene monomers.…”

The unique properties of nanocarbon materials – in particular, fullerenes – has led in recent years to the expansion of the spectrum of their application in various fields of the industry, including the chemical, energy, and pharmaceutical ones. The use of fullerenes in new industries poses new challenges to the scientific and research community. Thus, new methods of obtaining biocompatible liquid systems with small-sized monodisperse fullerene aggregates are still being sought. The paper focuses on the properties of fullerene solutions in mixtures of organic solvents, which serve as a basis for the development of new methods for synthesizing the aqueous liquid systems with fullerenes.
