A Straight Forward Route for the Development of Metal-Organic Frameworks Functionalized with Aromatic -OH Groups: Synthesis, Characterization, and Gas (N-2, Ar, H-2, CO2, CH4, NH3) Sorption Properties
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.
