Β-Cyclodextrin-Based Porous Organic Polymers for the Removal of Environmental Pollutants from Water

Abstract

As a macrocyclic host, β-cyclodextrin has a deep cavity of fixed size, as well as a unique internal hydrophobic and external hydrophilic cavity, which has excellent performance in host-guest recognition, and has been widely used in molecular recognition detection, drug delivery and other fields. Porous organic polymers have the characteristics of large specific surface area and pores, and have a good application prospect in the field of water pollution treatment.Therefore, the synthesis of β-cyclodextrin-based porous organic polymers not only has excellent host-guest recognition performance, but also has the characteristics of large specific surface area and multiple binding sites, so it has become the main design method at present. In this paper, the research status of β-cyclodextrin-based porous organic polymers in structural design and adsorption of pollutants was reviewed. The relationship between polymer structure design and adsorption performance was discussed, including adsorption of heavy metal ions and organic molecules in water. The application prospect and future development direction of β-cyclodextrin-based porous organic polymers were prospected.
