Metal−organic frameworks (MOFs), synthesized by assembling metal nods with organic linkers, are highly ordered crystalline materials. MOFs have attracted much attention for applications in electrochemical sensors, because of their unique chemical and physical properties including ultrahigh porosity, large surface area, tunable structure, and high thermal and chemical stability. In particular, redox and catalytic active sites introduced by use of active metal ions and/or ligands endow MOFs with the functions required in electrochemical sensing. Moreover, precise chemical modification of functional molecules and immobilization with metal nanoparticles, carbon nanostructures, and biomolecules could promote their electrochemical performances. In this Review, we focus on recent progress achieved in MOF research with respect to general sensing principles and analytical performances of electrochemical sensors. The evaluation and challenges governing the detection of the assays are also discussed.

金属有机骨架在电化学传感器中的应用

金属有机骨架（MOF）是通过将金属点与有机连接基组装而合成的，是高度有序的晶体材料。MOF由于其独特的化学和物理特性（包括超高孔隙率，大表面积，可调结构以及高热稳定性和化学稳定性）而在电化学传感器中引起了广泛关注。特别地，通过使用活性金属离子和/或配体引入的氧化还原和催化活性位使MOF具有电化学传感所需的功能。此外，功能分子的精确化学修饰和金属纳米颗粒，碳纳米结构和生物分子的固定化可以促进其电化学性能。在这篇评论中，我们专注于MOF研究中在一般感测原理和电化学传感器分析性能方面的最新进展。还讨论了评估和控制化验检测的挑战。
