Porous organic polymers: a progress report in China

Porous organic polymers (POPs) are porous materials composed of light elements such as C, H, N, and O. The benign characters, including large surface area, good physical and chemical stability, well-defined chemical composition, wide ranges of monomer selection, and strong designability, have made POPs one of the frontiers in materials research. In this review, we discussed the design and synthesis of various POP materials that mainly led by Chinese scientists, including conjugated microporous polymers (CMPs), porous aromatic frameworks (PAFs), and hypercrosslinked porous polymers (HCPs), as well as crystalline POPs comprised of covalent organic frameworks (COFs) and a special class of COFs with triazine rings, covalent triazine frameworks (CTFs), and supramolecular organic frameworks (SOFs), and sorted out their main applications in adsorption, separation, catalysis, and electrochemistry fields.
