Flexibility provides selectivity: The selective adsorption of CO2 from mixtures with N2, CH4, and N2O in a dynamic porous coordination polymer (see monomer structure) was evaluated by ATR-FTIR spectroscopy, GC, and SANS. All three techniques indicate highly selective adsorption of CO2 from CO2/CH4 and CO2/N2 mixtures at 30 °C, with no selectivity observed for the CO2/N2O system.
