Self-organization C₆₀ nanoparticles in toluene solution

The structure of fullerene C₆₀ in toluene solution was investigated both experimentally and theoretically in detail. C₆₀ was found to aggregate slowly even in fairly dilute solution concentrations ranging from 0.18 to 0.78 g/l at room temperature. The electronic absorption spectra obtained testify to the mainly molecular character of absorption. The aggregation kinetics results indicated that the structure of C₆₀ aggregates could be described as a fractal system. The numerical calculations predicted the formation of stable fullerene (C₆₀)N clusters in toluene solution with sizes >1.2 nm and aggregation number N≥3.
