用凝胶电泳法研究了一系列阴离子树枝状富勒烯衍生物与阳离子卟啉在缓冲水溶液中形成的静电耦合组装体。在这些调查中的中心利益是由分子，它们的大小，形状和自聚集携带的电荷量的变化。铁细胞色素c1和更刚性的锌卟啉作为ocacationic物种。合成了两个新的阴离子富勒烯衍生物3和6。在凝胶电泳实验中，富勒烯聚电解质3和4与1和2的静电复合物的形成是明显的。化合物，并显示出类似的行为对2。电泳实验证实了以前的结果与其他技术的定性水平，并提供了新的见解聚集现象。
The formation of electrostatically coupled assemblies of a series of anionic dendritic fullerene derivatives and cationic porphyrins in buffered aqueous media was studied with gel electrophoresis. Of central interest in these investigations was the variation of the amount of charge carried by the molecules, their size, shape and self-aggregation. Ferric cytochrome c 1 and the more rigid zinc porphyrin served as octacationic species. The two new anionic fullerene derivates 3 and 6 were synthesized. The formation of electrostatic complexes of the fullerene polyelectrolytes 3 and 4 with 1and 2 was clearly evident in the gel electrophoresis experiment. Compounds and showed a similar behaviour towards 2. The electrophoresis experiments confirmed previous results obtained with other techniques on a qualitative level and gave new insights into aggregation phenomena.
