| 摘 要： | Solvatochromism was observed in some solutions of C60 or C70, which was thought to arise from the formation of fullerene clusters[1—6]. This special type of solvato- chromism has aroused much interest because it has some potential applications in material science and sensor tech- nology. On the other hand, C60 or C70 can be made soluble in water by connecting it to various functional groups[7—20]. Those functionalized fullerenes not only have been found a number of important applicati…

| Abstract: | 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. |
