Background
Organic porous polymers are porous polymers formed by the covalent bonding of organic units. Compared with the classical porous materials (such as molecular sieves, mesoporous silicon and the like), the organic porous polymer has the greatest advantage that the pore size, the specific surface area and the pore channel environment of the organic porous polymer can be accurately regulated and controlled from the atomic scale by means of abundant diversity of organic building units and synthetic reactions, so that the organic porous frame structure with a specific structure and a specific function is obtained. Therefore, the organic porous frame structure has good application prospect in the interface chemistry fields of gas storage and separation, catalysis, sensing, energy storage, photoelectric conversion and the like.
