Benzyl Effects of Supramolecular Architectures Constructed by <i>p</i>-Sulfonatocalix[4]arene and Viologen Guests: from Simple 2:1 Complex to Polymeric Capsules

Two novel supramolecular assemblies have been constructed by p-sulfonatocalix[4]arene (C4AS) and viologen guests, showing that C4AS presents the supramolecular architecture of spectacular polymeric capsules in the presence of benzyl viologen, whereas it forms a simple host−guest 2:1 complex with methyl viologen.研究人员以对磺酰基杯[4]芳烃（p-sulfonatocalix[4]arene，C4AS）与紫精（viologen）客体为原料，构建了两种新型超分子组装体。实验结果表明，在苄基紫精（benzyl viologen）存在的条件下，C4AS可形成形貌引人注目的聚合物胶囊状超分子结构；而其与甲基紫精（methyl viologen）则仅生成简单的主客体2:1配合物。
