A new concept for constructing metal-organic frameworks (MOFs) based on multicenter-bonded [M ] (M=Mn, Zn) clusters with cubic aromaticity is discussed. In principle, intermolecular/intramolecular hydrogen-bonding, π-π stacking, coordinated covalent bonding and ionic bonding usually account for the structures of MOFs, and multicentered bonds generally exist in cation, anion, neutral and zwitterionic radicals, while rarely appear in MOFs. Meanwhile, aromaticity became one of the most vexing yet fascinating key concepts in chemistry since the proposition of the structure of benzene molecule in 1865. In this context, this concept article exhibits the preparation, structures, characterization methods, theoretical analysis of current research for MOFs which feature with multicentered bonding [M ] (M=Mn, Zn) cluster with cubic aromaticity, followed by their fluorescence probe and magnetic properties are also summarized. Finally, prospective outlook in this field is given.
讨论了一种基于具有立方芳香性的多中心键合[M]（M=Mn，Zn）簇的金属有机骨架（MOF）的新概念。原则上，分子间/分子内氢键、π-π堆积、配位共价键和离子键通常构成 MOF 的结构，而多中心键通常存在于阳离子、阴离子、中性和两性离子自由基中，而很少出现在 MOF 中。同时，自从 1865 年提出苯分子的结构以来，芳香性已成为化学中最令人困扰但又最迷人的关键概念之一。在这种情况下，本文展示了具有多中心键合[M]（M=Mn，Zn）簇的立方芳香性的 MOF 的制备、结构、特征方法、当前研究的理论分析，随后还总结了它们的荧光探针和磁性性质。最后，对该领域的前景进行了展望。
