Comprehensive Summary

Acetylene purification from methane is challenging in the field of porous organic polymers (POPs). Herein, we have provided one-pot Ullmann coupling reaction to synthesize a series of POPs with rich N-sites, named FJU-POP-n, wherein the low-cost and non-toxic Cu(acac)2 and environmental-friendly glycerol are employed as catalyst and solvent, respectively. These POPs constructed by aromatic amine and haloarene monomers exhibit different steric configurations and pore sizes. Among these, FJU-POP-4 with abundant N-functional sites and suitable pore size exhibits ultra-high selective separation for C2H2/CH4 (307.1, 50 : 50) at ambient conditions, the highest among the reported MOFs and POPs with nitrogen-sites as only functional species. Dynamic fixed bed breakthrough and regeneration experiments confirm structural stability and reproducibility, indicating their promising application in selective separation. image
