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.
通过凝胶电泳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性介质中静电偶联组装体的形成。这些研究的核心关注点是分子所带电荷量的变化、它们的大小、形状和自聚集情况。细胞色素c1和刚性更强的锌卟啉用作八价阳离子物种。合成了两种新型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形成静电复合物的现象清晰可见。化合物和对2表现出类似的行为。电泳实验在定性水平上证实了先前用其他技术获得的结果，并为聚集现象提供了新的见解。
