Synthesis methods of microporous organic polymeric adsorbents: a review

Microporous organic polymers (MOPs) have attracted the interest of researchers due to their good specific porosity, high surface area, light weight, and variable surface chemistry. A specific degree of porosity in polymers is a property that provides them with unique qualities and chances to be utilized in various technologically relevant applications. For example, depending on the size and chemical composition of the pores, the polymers may be used for selective adsorption and storage of specific molecules. Furthermore, they can be made as soluble networked materials or insoluble networked materials, depending on the functionality, monomers, and polymerization technique used. Therefore, metal and gas capture using microporous organic polymers seems promising; their large surface area and physicochemical stability are ideal for this application. This review summarizes the recent advances in the synthesis of MOPs, including covalent organic frameworks, hyper crosslinked polymers, conjugated microporous polymers, and covalent triazine-based frameworks, using a variety of techniques.
