Herein, we report the room temperature aqueous synthesis of the Zr(iv)-based metal-organic framework UiO-66 and a series of functionalized derivatives through postsynthetic exchange from a perfluorinated UiO-66-F4 precursor. All synthesized MOFs in this study were thoroughly characterized to verify formation of the desired MOF, porosity, crystallinity, and exchanged ligand content. This report represents a green, aqueous, room temperature synthesis of a highly valued series of Zr(iv)-based MOFs.
