High CO_2/N_2 and CO_2/CH_4 selectivity in a chiral metal-organic framework with contracted pores and multiple functionalities

摘要

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 CO_2/N_2 and CO_2/CH_4, indicating a synergistic effect of dynamic pores and functional groups.
