A facile and general methodology for the development of metal-organic frameworks (MOFs) functionalized with pendant, aromatic hydroxyl (-OH) groups is presented. Extensive gas-sorption studies in representative and important MOFs functionalized with free aromatic-OH groups such as the IRMOF-8 and DUT-6 (or MOF-205), denoted here as 1 and 2, revealed a high CO2/CH4 selectivity for 1 (13.6 at 273 K and 1 bar) and a high NH3 uptake of 16.4 mol kg-1 at 298 K and 1 bar for 2.
