Aggregation in C60/NMP, C60/NMP/water and C60/NMP/Toluene Mixtures

The solutions of C60 in N‐methyl‐2‐pyrrolidone (NMP) and in the binary mixtures NMP/water and NMP/toluene are investigated using UV‐Vis spectroscopy, small‐angle neutron scattering and mass‐spectroscopy. The decomposition of fullerene clusters after dilution of C60/NMP system with water and the effect of solvent polarity on fullerene aggregation in C60/NMP/toluene solutions are analyzed.
