An approach to the description of the growth of [C.sub.60] fullerene clusters in nitrogen-containing solvents has been proposed within the framework of the nucleation theory. A temporal solvatochromic effect and reorganization of fullerene clusters have been considered upon addition of water to the [C.sub.60]/N-methyl-2-pyrrolidone (NMP) system. In particular, the reorganization of fullerene clusters manifests itself as a sharp increase in the small-angle neutron scattering intensity for cluster sizes of the order of 10 nm. The conclusion has been drawn that, in order to explain these effects, it is necessary to take into account the formation of new (hypothetically, donor-acceptor) bonds between the [C.sub.60] and NMP molecules with time after the dissolution of fullerene.
