由多孔材料嵌入聚合物基质的杂化膜的制备是一个热门的主题。在此，我们介绍了一类新的杂化膜：超交联金属有机多面体（HCMOP）。这些膜基于可溶性MOPs，其可以作为超交联聚合物网络中的高连通性节点。HCM 0 P自发地形成宏观尺度的、无缺陷的、独立的膜，并且由于MOP的共价交联，所得膜具有多种功能：强透水性;自修复能力;抗微生物活性;以及比原始聚亚胺膜更好的分离和机械性能。本研究为多功能膜的设计和制备提供了新的思路，同时也拓宽了MOPs的应用领域。
Fabrication of hybrid membranes composed of porous materials embedded in polymer matrices is a subject of topical interest. Herein, we introduce a new class of hybrid membranes: hyper-cross-linked metal-organic polyhedra (HCMOPs). These membranes are based upon soluble MOPs that can serve as high-connectivity nodes in hyper-cross-linked polymer networks. HCMOPs spontaneously form macro-scale, defect-free, freestanding membranes, and, thanks to the covalent cross-linking of MOPs, the resulting membranes possess multiple functionalities: strong water permeability; self-healing ability; antimicrobial activity; and better separation and mechanical performance than pristine polyimine membranes. This study introduces a new concept for the design and fabrication of multifunctional membranes and also broadens the applications of MOPs.
