摘要 Water-soluble N,N-dimethyl[60]fulleropyrro-lidinium iodide (C60(C4H10N+)I-), when dissolved in binarymixtures of tetrahydrofuran and water, was found to exhibit remarkable solvatochromism. Correspondingly, the UV-vis spectra showed obvious changes by variation of the solventcomposition of tetrahydrofuran and water. It was found that both concentration and temperature had strong influence on the stability of monomer-state C60(C4H10N+)I-, while theyhad little effect on the stability of aggregated C60(C4H10N+) I-The formation of cluster was confirmed by TEM and AFMmeasurements.
