By stepwise functionalization of a T-shaped ligand with amide and N-oxide groups, we obtained a MOF with drastically strengthened CO2-framework interactions, induced by a "open donor sites" (ODSs) effect, resulting in a high heat of adsorption and high CO2/CH4, CO2/CO and CO2/N2 separation selectivities at room temperature.
通过用酰胺和N-氧化物基团对T形配体进行逐步官能化，我们获得了一种金属有机框架（MOF），其因“开放供体位点”（ODSs）效应而使二氧化碳与框架之间的相互作用大幅增强，从而在室温下具有高吸附热以及高的二氧化碳/甲烷、二氧化碳/一氧化碳和二氧化碳/氮气分离选择性。
