Slow aggregation of buckminsterfullerene (C60) in benzene solution

Abstract Solution behavior of buckminsterfullerene (C60) in benzene was investigated by laser light scattering using an incident wavelength of 790 nm. C60 was found to aggregate slowly even in fairly dilute solution concentrations ranging from 1.39 to 2.11 mg/ml at room temperatures (23–26°C). The aggregation of C60 in benzene solution was reversible. The C60 aggregates could be dispersed simply by hand shaking the solution. The light-scattering intensity results indicated that the structure of C60 aggregates could be described as a fractal with dimension of 2.10 and the aggregation kinetics exhibited essentially an exponential behavior.
