Boosting Adsorption and Selectivity of Acetylene by Nitro Functionalisation in Copper(II)-Based Metal-Organic Frameworks.

ABSTRACT: Purification and storage of acetylene (C₂H₂) are important to many industrial processes. The exploitation of metal-organic framework (MOF) materials to address the balance between selectivity for C₂H₂ vs carbon dioxide (CO₂) against maximising uptake of C₂H₂ has attracted much interest. Herein, we report that the synergy between unsaturated Cu(II) sites and functional groups, fluoro (-F), methyl (-CH₃), nitro (-NO₂) in a series of isostructural MOF materials MFM-190(R) that show exceptional adsorption and selectivity of C₂H₂. At 298 K, MFM-190(NO₂) exhibits an C₂H₂ uptake of 216 cm³ g^-1 (320 cm³ g^-1</
