Polymeric metal-organic nanocapsule networks (polyMONCs), where metal-organic nanocapsules (MONCs) are connected by functional polymers, could possess the properties of traditional polymers and also retain the structures of MONCs. In this work, we constructed novel polyMONCs based on Mg-seamed pyrogallol[4]arene-containing MONCs through supramolecular coordination-driven self-assembly. The MONCs can be successfully polymerized using poly(ethylene glycol) as the linker, and the prepared polyMONCs can be further made into gels with self-healing properties and stimuli responsiveness. Advantageously, single crystals of MONCs cross-linked by ethylene glycol/diethylene glycol were obtained, giving us direct perspectives to mimic and investigate the self-assembly process of polyMONCs.
高分子金属-有机纳米胶囊网络（polyMONCs），其中金属-有机纳米胶囊（MONCs）由功能聚合物连接，可能具有传统聚合物的性质，同时保留 MONCs 的结构。在这项工作中，我们通过超分子配位驱动的自组装，构建了基于含有镁缝接的焦倍酚[4]芳烃的 MONCs 的新型 polyMONCs。可以使用聚（乙二醇）作为连接物成功聚合 MONCs，并且制备的 polyMONCs 可以进一步制成具有自修复性能和刺激响应性的凝胶。有利的是，通过乙二醇/二乙二醇交联的 MONCs 单晶得以获得，这使我们能够直接模拟和研究 polyMONCs 的自组装过程。
