The construction of hydrogen-bonded organic framework materials by intermolecular hydrogen bonding forces has been rapidly developed in the last decade, among which, the strong intermolecular hydrogen bonding and functional binding sites exhibited by nitrogen-containing functional groups have made them favorites for designing organic components to customize functionalized porous materials. This review systematically introduces the types of nitrogen-containing monomers used to prepare porous hydrogen-bonded organic backbones and the principles of their construction, summarizes the design advantages of crystalline materials from an elemental perspective, and presents the applications of such HOFs in the fields of gas adsorption/separation, molecular recognition, plasmonic conductivity, biomedical, and luminescent materials, etc. Finally, the prospects for the development of such materials are discussed and potential directions for future work are analyzed.
Keywords: functionalized; hydrogen-bonded organic framework materials; nitrogen-containing functional groups; porous materials.
