A novel heteroditopic A-B monomer was synthesized and used to construct linear supramolecular polymers utilizing pillar[5]arene-based host-guest interactions. Specifically, upon addition of Cu(2+) ions, the supramolecular polymer chains are crosslinked through metal-ligand interactions, resulting in the formation of a supramolecular polymer gel. Interestingly, this self-organized supramolecular polymer can be used as a novel fluorescent sensor for detecting Cu(2+) ions.
合成了一种新型的异双位点A-B单体，并利用基于柱[5]芳烃的主客体相互作用构建线性超分子聚合物。具体而言，加入Cu(2+)离子后，超分子聚合物链通过金属-配体相互作用交联，形成超分子聚合物凝胶。有趣的是，这种自组装的超分子聚合物可用作检测Cu(2+)离子的新型荧光传感器。
