High CO2/N2 and CO2/CH4 selectivity in a chiral metal-organic framework with contracted pores and multiple functionalities.
A metal-organic framework with chiral pores and decorated imidazole and methyl groups was constructed. Upon activation, this MOF undergoes a pore contraction and shows very high selectivity for CO2/N2 and CO2/CH4, indicating a synergistic effect of dynamic pores and functional groups.
