Recent Development of Hypercrosslinked Microporous Organic Polymers

Hypercrosslinked polymers (HCPs) are currently receiving great interest due to their easy preparation, high chemical and thermal stability, and low cost. Combined with the lightweight properties and high surface areas HCPs can be considered as promising materials for gas storage and separation, catalysis, and heavy metal ions removal in wastewater treatment. This Feature Article summarizes strategies for the preparation of HCPs, comprising the post‐crosslinking of “Davankov‐type” resins, direct polycondensation of aromatic chloromethyl (or hydroxymethyl) monomers, and knitting aromatic compound polymers (KAPs). The HCPs applications, such as H2 storage, CO2 capture, and heterogeneous catalysis, are also discussed throughout in the article. Finally, the outlook of this research area is given. Hypercrosslinked microporous organic polymers, one of the most studied porous materials, have attracted more and more research interest in recent years. They exhibit high specific surface areas, good thermal stability, and low costs. New research trends in the synthetic strategies, the gas uptake, and catalyst application of the hypercrosslinked polymers are summarized.
