| Abstract |
Compare to other porous materials, (e.g. mesoporous silica, zeolites, etc.), the organic functional groups could be installed into the frameworks relatively easily via organic transformations on the organic linker part of metal-organic frameworks (MOFs). This functional groups diversity is one of the great advantages of MOFs.
Recently, we have successfully installed various combinations of two different functional groups in MOF pore. The NH2-, Cl- (or halogen), MeO-, and NO2- groups were selectively installed on benzene-1,4-dicarboxylic acid (BDC) with region-selective manners and applied them to MOF synthesis. Very interestingly, the structural flexibility (i.e., breathing behavior of framework) was totally changed by regioisomeric positional controls in some specific combinations. Particularly, we have found that the combinations of NH2-Cl, NH2-OMe, OMe-OMe only produced the flexible frameworks when they were placed in para-position.[1-3]
In this presentation, our recent studied for the physical property changes (i.e., flexible changes or breathing behavior changes) by regioisomerism in MOFs will be summarized and deeply discussed. The structural flexibility changes of MOFs through ligand positioning controls will be presented with ligand synthesis and characterization along with MOF characterizations.
