Versatile Flexible Azolate-based Metal-Organic Frameworks Possessing Different Bridging Ligands

Tiance AN, Zhang L

Many MOFstructures, especially three-dimensional ones are usually rigid mainly due to the utilization of rigid ligands such as terephthalic acid, making the robust framework difficult to remain the integrity under structure variations or against acidic/basic media. In order to solve the problem as well as enhance the chemical and thermal inertness of MOFs, we have designed to synthesize MOF structures using the semirigid ligand, 3,3’,5,5’-tetramethyl-4,4’-bipyrazole (H2Me4bpz), as the two pyrazolate (pz) rings can rotate around its C-C chemical bond so that can release some of the pressure caused by structure variations. We chose CuCl2 and ZnSO4 as the metal source and successfully synthesized two novel porous MOFs through solvothermal reaction with H2Me4bpz.
