Two metal-organic frameworks (MOFs), trans-[Co(L)(μ₂-H₂O)(H₂O)₂]·2H₂O (1) and cis-[Mn(L)(Bipy)] (2) (H₂L=2, 2′-dimethyl-4, 4′-biphenyldicarboxylic acid, Bipy=4, 4′-bipyridine), have been synthesized and characterized by FTIR, thermogravimetric analysis (TGA), powder and single crystal X-ray diffraction. MOF 1 crystallizes in the triclinic system with a P1 space group and contains two crystallographically different Co(Ⅱ) ions. Each trans-[CoO₆] octahedron is connected by μ₂-H₂O and L^2- ligand with a bis(unidentate) coordination mode to produce a 2D sql topological network. MOF 2 crystallizes in the monoclinic system with a C2/c space group. The Mn(Ⅱ) cation adopts a cis-[MnO₄N₂] octahedron as a 6-connected node and is linked by L^2- ligand as a 4-connected node to generate a binodal (4, 6)-connected 3D fsc framework. The intermolecular interactions in 1 and 2 have been investigated by 3D Hirshfeld surface analyses and 2D fingerprint plots to reveal that the main interactions are H…H and O…H/H…O contacts in 1, and H…H and C…H/H…C contacts in 2. The TGA indicated that 1 and 2 were stable below 390 and 370 ℃, respectively.

2025年诺贝尔化学奖授予S. Kitagawa、R. Robson和O. M. Yaghi，以表彰他们在金属有机框架(Metal-Organic Frameworks，MOFs)开发方面的成就。作为21世纪的明星材料，MOFs因其巨大的比表面积、纳米级孔道以及多样的拓扑结构，在众多领域得以应用。作为最先进的多孔材料，MOFs的应用不再局限于气体吸附、分离和催化等传统领域，在大气集水、病原体检测和海水提铀等新兴领域也展现出广阔的应用前景。2013年，Yaghi在Science上发表了一篇有关MOFs最佳性能的重要综述。但从那以后，MOFs的性能又取得了重大突破。通过网状化学原理指导无机阳离子(节点)与有机配体(连接体)的组装，可以构筑混合组分的MOFs，使单组分MOFs优异性能的协同组合得以实现。将人工智能技术引入MOFs领域，能够为科学家们提供更多的机会，以快速设计和制造具有定制性能的新型MOFs。此外，基于反向MOFs设计策略(带负电荷的节点和带正电荷的配体)合成的新型多孔等网状non-MOFs材料将为MOFs材料开辟一个新的研究热点。
