Sulfur-Containing Metal-Organic Framework

Abstract

Metal-organic frameworks (MOFs) have garnered significant attention from scientists due to their unique chemical structures, high amenability to post-synthetic modification, and their ability to combine the rigidity of inorganic materials with the flexibility of organic components. These characteristics endow MOFs with promising application prospects across numerous fields. Sulfur atoms, characterized by their relatively high electronegativity, large atomic radius, and versatile coordination capabilities, can impart a series of distinctive alterations to material properties, thereby attracting widespread interest. Incorporating sulfur into the organic ligands of MOFs modifies a range of their physicochemical properties, leading to unique changes such as enhanced metal ion adsorption, altered catalytic performance, and modified gas adsorption and separation capabilities. This review discusses the influence of sulfur incorporation on the structure and properties of MOF materials, the strategies employed to introduce sulfur into MOFs, and the applications of sulfur-containing MOFs
