氢键芳酰胺基元逐级组装为折叠体、大环与笼状结构以放大碘吸附
Progressive Organization of Hydrogen‐Bonded Aramide Motifs via Foldamer–Macrocycle–Cage Architectures for Amplified Iodine Capture
AI 导读
研究将同一氢键芳酰胺基元逐级组织为无环折叠体、大环和笼状三种架构，碘吸附容量、动力学与保持率沿该序列逐步提升。按芳酰胺基元数归一化后，每个基元的吸附贡献也随架构升级而增加，表现为非加和的放大效应；在100倍竞争阴离子过量条件下，单个笼状分子最多捕获84个I3−。结构与计算分析将这一行为主要归因于逐级架构组织强化了基元层面的主客体相互作用，固态堆积则调节吸附空间的分布与可及性。
推荐理由
同一氢键芳酰胺基元被逐级组装成无环折叠体、大环与笼状结构，读者可看到架构层级如何改变碘吸附容量与动力学。
