Green synthesis and processing of porous organic materials

• Porous organic materials (POMs), including amorphous porous organic polymers (POPs) and crystalline covalent organic frameworks (COFs), are emerging functional porous materials with unique properties such as high surface areas, tunable porosities, and synthetic diversity. They have attracted significant attention for their potential applications in adsorption, separation, catalysis, energy harvesting, and storage. However, their practical use has been hampered by the high synthesis cost, complicated synthesis procedures, and challenges in material processing.To address these limitations, we have recently developed a cost-effective, environmentally friendly, and scalable method for synthesizing imine and aminal linked POPs using industrially available organic linkers in ethanol/water at room temperature. Additionally, a range of imine linked COFs has been synthesized in aqueous solutions at room temperature. Furthermore, we have employed interweaving and interfacial synthesis techniques to process POMs into freestanding nanopapers, utilizing cellulose fibers as a substrate material. These nanopapers demonstrate potential applications as membranes for the removal of antibiotics from wastewater and the capture of gold ions from electronic waste leaching solutions. These advancements offer new possibilities for large-scale synthesis, processing, and the practical application of POMs.
