| Abstract |
Metal-Organic Frameworks are porous crystalline materials in which organic ligands link metal ion or metal cluster. Compared to other porous materials, relatively easily, the target functional groups could be installed to organic linkers. Nowadays, MOFs have applied for various applications such as gas storage, separation, catalysis, etc.
Recently, we have focused on the introduction of two chemical functional groups into an organic linker of MOFs in regioisomeric methods. We have selectively installed the NH2-, Cl-, MeO-, NO2- groups to BDC ligand and obtained two regioisomeric ligands (ortho- and para-disubstituted BDC). Total sixteen, di-substituted ligands were incorporated into DMOF pore, and fourteen DMOFs were successfully obtained and characterized by PXRD and NMR analysis. Specially, we have found that the two para-positional combinations of NH2-OMe, OMe-OMe produced the flexible frameworks among the fourteen MOFs.1-3
In addition, using these ligand systems, we have synthesized multi-functional Zr-MOFs and applied tham to Xe/Kr separation. 4 Interestingly, the electronic density of ligand is highly correlated with Xe/Kr separation efficiency. Finally, we are pleased to discuss about the additional regioisomeric controls in BDC ligands and their correlation to flexibility of MOFs during the presentation.
