Metal-induced ordered microporous polymers (MMPs), a class of porous polymer, are synthesized from amine-bearing polymers, small organic linkers and divalent metal ions using a polymer-directed chemical synthesis process. Specifically, small organic linkers first coordinate to metal ions, with the resulting unit cells then self-assembling along the extension of polymer chains to construct three-dimensional frameworks. The MMPs demonstrate good controllability of crystal and framework size, as well as hydrolytic stability. MMP dispersions were coated on a modified polysulfone substrate to fabricate MMP/mPSf membranes with an ultrathin selective layer (below 50 nm) and surface areas of >100 cm². The MMPs are readily fabricated into defect-free thin selective-layered membranes with high CO₂ permeance (3,000 GPU) and stable CO₂/N₂ selectivity (78) under both humid and dry gas feed conditions, demonstrating promising CO₂ membrane separation performance. This synthetic methodology could be extended to other polymers, potentially enabling facile synthesis of membrane materials.

金属诱导的有序微孔聚合物（MMPs）是一类多孔聚合物，是使用聚合物定向化学合成方法由含胺聚合物，小的有机连接基和二价金属离子合成的。具体来说，小的有机连接基首先与金属离子配位，然后生成的晶胞沿着聚合物链的延伸自组装以构建三维框架。MMPs表现出良好的晶体可控性和骨架尺寸，以及水解稳定性。将MMP分散体涂布在改性的聚砜基材上，以制造具有超薄选择性层（低于50 nm）且表面积> 100 cm ^2的MMP / mPSf膜。MMP易于制造成具有高CO ₂的无缺陷薄选择层膜在潮湿和干燥气体进料条件下的渗透性（3,000 GPU）和稳定的CO ₂ / N ₂选择性（78），证明了有希望的CO ₂膜分离性能。这种合成方法可以扩展到其他聚合物，潜在地实现膜材料的简便合成。
