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

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 ami...

Summary: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.
