| Abstract |
Metal-organic frameworks (MOFs) are solid material consisted by coordination bonds between metal clusters (e.g., secondary building units, SBUs) and organic linkers.[1] Recently, it was revealed that the coordination bonds between SBU and carboxylic acid on MOFs is in dynamics, and the exchange phenomenon was successfully applied to ‘functionalization methods’ for MOFs. Both cations and ligands could be incorporated into MOF structures, and several experimental data supports this observation follows the exchanges process and not dissolution/re-aggregation process.[2,3]
In this presentation, our recent studies about postsynthetic ligand exchange (PSE) on a zirconium-based MOF, UiO-66 (UiO = University of Oslo) with some mechanistic clues will be presented. We have examined that target ligand effects, parent MOF effects, and structural defect effects to obtain the mechanistic evidence for PSE. In addition, the sequential PSEs were performed to prepare multi-layer type or core-shell type MOFs with three different ligands. The detail preparation methods for ligand and PSE procedures will be discussed along with kinetic data.
