Thermochemical Insights into Fullerene Aggregation and the Phthalocyanine–Fullerene Interaction in Efficient Solvents

Abstract

The physicochemical behavior of fullerene C in hydrocarbon solvents is examined by isothermal titration calorimetry, photocalorimetry, and UV spectroscopy. The obtained data are summarized to substantiate the idea of the binary fullerene/solvent cluster as a colloidal nanoentity that moderates noncovalent interactions of the C molecule in solution. This idea serves to aid understanding of the complex physicochemical behavior of tert-butyl-substituted phthalocyanine in C -saturated o-xylene under illumination with low-energy photons. The proposed experimental approach, which focuses on concentrated solutions and is applicable to multicomponent systems, is discussed as a potential tool of materials science.

The formation of self-assembled structures of C60 in solution and in the volume of an evaporating drop of a colloidal solution

“…In a number of pure and mixed organic solvents, fullerene С n (n = 60, 70, 76, …) molecules show a pronounced tendency to self-assembly and the formation of fairly large functional fullerene aggregates of various shapes and sizes. The problem was fundamentally studied by different physical and chemical methods in [3][4][5][6][7][8][9][10][11] and the obtained results provided a vector toward potential applications in material chemistry [12,13], biomedicine [14][15][16], phototherapy [17][18][19], molecular electronics [20], optoelectronics [21,22] and solar energy [23][24][25].…”
