Metal–organic frameworks (MOFs) have evolved to be next-generation utility materials because of their serviceability in a wide variety of applications. Built from organic ligands with multiple binding sites in conjunction with metal ions/clusters, these materials have found profound advantages over their other congeners in the domain of porous materials. The plethora of applications that these materials encompass has motivated material chemists to develop such novel materials, and the catalogue of MOFs is thus ever-escalating. One key feature that MOFs possess is their responsiveness toward incoming guest molecules, resulting in changes in their physical and chemical properties. Such uniqueness generally arises owing to the influenceable ligands and/or metal units that govern the formation of these ordered architectures. The suitable host–guest interactions play an important role in determining the specific responses of these materials and thus find important applications in sensing, catalysis, separation, conduction, etc.

来宾反应灵敏的金属有机框架，用作分离和传感应用的支架

金属有机框架（MOF）已发展成为下一代实用材料，因为它们可在多种应用中使用。这些材料是由具有多个结合位点的有机配体与金属离子/簇结合而成，在多孔材料领域中，与其他同类物相比，它们具有深远的优势。这些材料所包含的众多应用促使材料化学家开发这种新颖的材料，因此，MOF的目录在不断增加。MOF的主要特征之一是它们对传入的客体分子的响应能力，从而导致其物理和化学性质发生变化。由于控制这些有序体系结构的形成的可影响的配体和/或金属单元，通常产生这种独特性。
