In the work, the behavior of C60 fullerene molecules in benzene and in a binary benzeneisopropyl alcohol (IPA) system was experimentally investigated using optical spectroscopy,IR-spectroscopy, and dynamic light scattering (DLS). It was shown that the addition of IPAsignificantly changes the optical characteristics of the solution: the disappearance of the bandat region of 391 nm and the broadening of the transition in the 407 nm indicate a transition ofC60 molecules from a monomeric state to an aggregated one. Analysis of the IR-spectra revealed shifts of the characteristic vibrational modes of C60, which is associated with changes inthe dielectric properties of the medium and an enhancement of dipole-induced interactionsbetween molecules. DLS measurements confirmed an increase in cluster sizes: the averagehydrodynamic diameter increases from ~53.8 nm in the C60-benzene solution to ~143.6 nm inthe C60-benzene-IPA system, indicating enhanced self-organization and the formation of largernanostructures. Data analysis shows that fullerene aggregation in binary solvents is determinedby both the nature of the solvent and its polarity, and that changing the medium compositionmakes it possible to control the degree of molecular self-organization
