CO<sub>2</sub>-selective molecular recognition in UiO-66 <i>via</i> post-synthetic polyethylene glycol/amidoxime functionalization
A diisocyanate-bridged polyethylene glycol modification and time-controlled amidoximation strategies are developed to engineer UiO-66 metal-organic frameworks (MOFs), achieving 115.3% and 130.0% CO<sub>2</sub>/N<sub>2</sub> adsorption selectivity enhancements <i>via</i> escalated CO<sub>2</sub>-MOF interactions. This universal approach could be accommodated in diverse MOF systems for tailored carbon capture and separation applications.
