在过去的20年里，多孔材料领域取得了巨大的进步，包括新型金属有机框架（MOFs）的开发，这些框架在解决全球环境和工业挑战的实际应用中显示出巨大的潜力。实现这一进展的一个关键工具是网状化学，通过它，研究人员可以设计出具有高度规则性的材料（即，边传递）拓扑，基于几何匹配的构建块组装成特定的网络。然而，创新有时要求研究人员远离默认拓扑结构，转而追求不寻常的几何形状。在这个角度，我们涵盖了这方面，并介绍了几何不匹配的概念，其中看似不兼容的构建块相结合，以产生非默认结构。我们描述了通过使用配体弯曲角、扭曲官能团、锯齿形配体和其他元素产生的几何失配构建的各种MOF组装体，重点是基于羧酸根的MOF与常见的无机簇结合。我们的目标是提供一个新的观点，合理设计的MOFs，并帮助读者了解无数的选择，现在可以实现更大的结构复杂性的MOFs。
The past 20 years have witnessed tremendous advances in the field of porous materials, including the development of novel metal-organic frameworks (MOFs) that show great potential for practical applications aimed at addressing global environmental and industrial challenges. A critical tool enabling this progress has been reticular chemistry, through which researchers can design materials that exhibit highly regular (i.e., edge-transitive) topologies, based on the assembly of geometrically matched building blocks into specific nets. However, innovation sometimes demands that researchers steer away from default topologies to instead pursue unusual geometries. In this Perspective, we cover this aspect and introduce the concept of geometry mismatch, in which seemingly incompatible building blocks are combined to generate non-default structures. We describe diverse MOF assemblies built through geometry mismatch generated by use of ligand bend angles, twisted functional groups, zigzag ligands and other elements, focusing on carboxylate-based MOFs combined with common inorganic clusters. We aim to provide a fresh perspective on rational design of MOFs and to help readers understand the countless options now available to achieve greater structural complexity in MOFs.
