Research Progress in Hypercrosslinked Microporous Organic Polymers

Hypercrosslinked microporous polymers are currently an important class of porous polymer materials and receiving great interest due to their advantages such as high surface area, moderate synthetic conditions and diverse building blocks. According to the difference between the synthetic methods, hypercrosslinked polymers are mainly prepared by the following three strategies: polymer precursor post-crosslinking, one-step self-polycondensation of multifunctional monomers and external crosslinker knitting rigid aromatic compounds. In this review, we introduce the development of hypercrosslinked polymer in detail as well as investigate various synthetic methods and polymer networks with controlled micro-morphology, the broad practical and potential applications including gas storage, adsorption, separation and heterogeneous catalysis were also discussed. In the end, we talk about the disadvantage of hypercrosslinked polymers and challenges in the future as well as predict the further development on synthesis and application.
