Azo-functionalized microporous organic polymers: synthesis and applications in CO2 capture and conversion

Azo-functionalized MOPs (Azo-MOPs) were synthesized via oxidative polymerization of aromatic amines catalyzed by t-BuOCl/NaI (25 degrees C, 1 h, yield: >95%), which displayed an excellent coordinating ability with a Ru complex. The resulting Ru-coordinated Azo-MOPs displayed high CO2 capacity and high performances for catalyzing the methylation of amines with CO2 under low pressure (0.5 MPa).
