Porous organic polymers (POPs), featured as a new class of advanced porous materials, have received intense research interests owing to their advantages of inherent porosity, robust scaffolds, high surface areas, tunable structure and tailor-made function. Among them, macrocyclic porous organic polymers, are derived from natural-occurring or synthetic macrocyclic compounds as the basic building blocks. Relative to common POPs, macrocyclic POPs posse hierarchical porous structures with the combination of inherent cavity from the macrocycles, and extended porous frameworks generated during polymerization. Attributed to this hierarchical porous structure, the host-guest interactions of macrocyclic POPs are further enhanced with well-defined voids. And these macrocyclic porous materials have also shown great potentials in environmental remediation, gas adsorption, heterogeneous catalysis, fluorescent sensing and ionic conduction . Among the reported macrocyclic POPs, conventional macrocyclic compounds, including cyclodextrin, crown ether, calix [4]arene and pillararene, are widely used toward introducing specific supramolecular binding sites into the porous skeleton. The well-established host-guest interaction for these host molecules have been well transplanted into the macrocy-clic POPs. In order to endow task-specific functions beyond supramolecular chemistry, functional macrocycles, like porphyrin, arylene-ethynylene macrocycles, cyclotriveratrylene, and others, are also leveraged to introduce electronic-active or catalytic sites into the functional macrocyclic POPs.
