Abstract

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% CO₂/N₂ adsorption selectivity enhancements via escalated CO₂–MOF interactions. This universal approach could be accommodated in diverse MOF systems for tailored carbon capture and separation applications.
