Robust multivariate metal-porphyrin frameworks for efficient ambient fixation of CO2 to cyclic carbonates

Article abstract of DOI:10.1039/c8cc07865c

A family of multivariate metal-organic frameworks (MOFs) with three-kinds of orderly distributed metals were designed and successfully synthesized by combining metalloporphyrin sheets and pentafluoride (NbOF₅)^2? pillars. Benefiting from the cooperative nature of open-metal-sites (OMSs) within porphyrins, specific pore-sizes, coupled with fluorine-rich electrostatic environments, the fabricated materials demonstrated high affinity toward CO₂, and good catalytic performance, structural robustness, and good recyclability for the conversion of epoxides and CO₂ to cyclic carbonates at room temperature and 1 atm pressure.
