Positional Installation of Unsymmetrical Fluorine Functionalities onto Metal–Organic Frameworks for Efficient Carbon Dioxide Separation under Humid Conditions

Abstract

Unsymmetrical trifluoro functional groups were installed onto metal–organic frameworks (MOFs) at positions regulated by ligand exchange for efficient CO₂ separation under humid conditions. These trifluoro groups induced molecular separation via dipole–dipole interactions. Their installation onto amino-functionalized MOF surfaces produced hydrophobic and CO₂-philic core–shell MOFs for efficient CO₂ adsorption.
