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 2 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 1 and 2 was clearly evident in the gel electrophoresis experiment. Compounds 5 and 6 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.
研究了在缓冲水介质中一系列阴离子树状富勒烯衍生物与阳离子卟啉的静电耦合组装的形成,采用了凝胶电泳技术。这些研究的中心兴趣在于分子所携带的电荷量的变化、它们的大小、形状及自聚集性。三价细胞色素c 1和更为刚性的锌卟啉2作为八阳离子物种。合成了两种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显而易见。化合物5和6对2表现出类似的行为。电泳实验确认了之前利用其他技术获得的定性结果,并为聚集现象提供了新的见解。
