Optimizing zirconium metal–organic frameworks through steric tuning for efficient removal of Cr2O72

A ligand with a flexible conformation can be obtained by modifying functional groups. We modified H4DCBA with –CH3/–CF3 groups to construct three Zr-MOFs; the torsion of the central benzene ring changes the topologies. The three Zr-MOFs showed high adsorption rates for Cr2O72−, and the CF3-functiona...

Summary:A ligand with a flexible conformation can be obtained by modifying functional groups. We modified H4DCBA with –CH3/–CF3 groups to construct three Zr-MOFs; the torsion of the central benzene ring changes the topologies. The three Zr-MOFs showed high adsorption rates for Cr2O72−, and the CF3-functional groups enhanced the adsorption capacity of UPC-49 for Cr2O72−.
