The exploitation of metal\u2013organic framework (MOF) materials to address the balance between selectivity for C\n 2<\/jats:sub>\n H\n 2<\/jats:sub>\n vs<\/jats:italic>\n carbon dioxide (CO\n 2<\/jats:sub>\n ) against maximising uptake of C\n 2<\/jats:sub>\n H\n 2<\/jats:sub>\n has attracted much interest. Herein, we report that the synergy between unsaturated Cu(II) sites and functional groups, fluoro (\u2212F), methyl (\u2212CH\n 3<\/jats:sub>\n ), nitro (\u2212NO\n 2<\/jats:sub>\n ) in a series of isostructural MOF materials MFM\u2010190(R) that show exceptional adsorption and selectivity of C\n 2<\/jats:sub>\n H\n 2<\/jats:sub>\n . At 298\u2005K, MFM\u2010190(NO\n 2<\/jats:sub>\n ) exhibits an C\n 2<\/jats:sub>\n H\n 2<\/jats:sub>\n uptake of 216\u2005cm\n 3<\/jats:sup>\n \u2009g\n \u22121<\/jats:sup>\n (320\u2005cm\n 3<\/jats:sup>\n \u2009g\n \u22121<\/jats:sup>\n at 273\u2005K) at 1.0\u2005bar and a high selectivity for C\n 2<\/jats:sub>\n H\n 2<\/jats:sub>\n \/CO\n 2<\/jats:sub>\n (up to ~150 for v\/v = 2\/1) relevant to that in the industrial cracking stream.
