Responsive synthetic receptors for adaptive recognition of different ionic guests in a competitive environment are valuable molecular tools for not only ion sensing and transport, but also the development of ion-responsive smart materials and related technologies. By virtue of the mechanical chelation and ability to undergo large-amplitude co-conformational changes, described herein is the discovery of a chameleon-like [2]catenane that selectively binds copper(I) or sulfate ions and its associated co-conformational mechanostereochemical switching. This work highlights not only the advantages and versatility of catenane as a molecular skeleton in receptor design, but also its potential in constructing complex responsive systems with multiple inputs and outputs.
在竞争环境中对不同离子客体进行适应性识别的响应性合成受体，不仅是用于离子传感和传输的有价值分子工具，也是用于开发离子响应智能材料及相关技术的有价值分子工具。凭借机械螯合作用以及经历大幅度共构象变化的能力，本文报道了一种类变色龙[2]索烃的发现，该索烃能选择性结合铜（I）或硫酸根离子及其相关的共构象机械立体化学转换。这项工作不仅突出了索烃作为受体设计中分子骨架的优势和多功能性，还突出了其在构建具有多个输入和输出的复杂响应系统方面的潜力。
