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.
