Porous Organic Polymers Incorporating Shape-Persistent Cyclobenzoin Macrocycles for Organic Solvent Separation.

The recovery and separation of organic solvents is highly important for the chemical industry and environmental protection. In this context, porous organic polymers (POPs) have significant potential owing to the possibility of integrating shape-persistent macrocyclic units with high guest selectivity. Here, we report the synthesis of a macrocyclic porous organic polymer (np-POP) and the corresponding model compound by reacting the cyclotetrabenzil naphthalene octaketone macrocycle with 1,2,4,5-tetraaminobenzene and 1,2-diaminobenzene, respectively, under solvothermal conditions.
