氨基酸功能化晶态多孔聚合物的研究进展

Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) are representative crystalline porous polymers. Due to their high surface area, high porosity, open channels, abundant functional groups and easy functionalization, they show great applications in gas storage and separation, catalysis, energy storage, photovoltaic devices, etc. Amino acids are the basic structural units that constitute peptides and proteins, which not only have important biological functions, but also play an important role in industrial applications such as pharmaceutical production, biodegradable plastics, and chiral catalysts. The introduction of amino acids into MOFs and COFs could endow them with diverse and flexible frameworks, special pore environment, and chiral sites, improving their biocompatibility and degradability to some extent and enriching their functions and applications. This review focuses on the progress of the amino acid functionalized MOFs and COFs, including their synthetic strategies, such as employing amino acids and their derivatives as building unit, covalent modification of amino acids onto the framework, and utilizing amino acids as modulators. The advantages and disadvantages of these strategies are compared and their challenges are discussed. In addition, we also introduce their applications in chiral separation, catalysis, adsorption and proton conduction. Finally, we summarize the current challenges in the preparation of amino acid functionalized crystalline porous polymers and outlook the future research direction in this field.
