Metal-organic frameworks (MOFs) are a relatively new class of highly tunable materials with potential applications in gas storage and separation, sensing, and heterogeneous catalysis. However, the poor chemical and thermal stability of many carboxylate-based MOFs presents an obstacle to their development for many of these applications. We have recently synthesized two new MOFs constructed from 4,4’-bis(3,5-dimethylpyrazolyl)biphenyl ([(Me2pyz)2biPh]2-) linkers and Co2+ (1) or Zn2+ (2). MOF 1, which has been structurally characterized by single crystal X-ray diffraction, is an isoreticular analogue of previously reported MFU-1 (Co4O(bdpb)6; bdpb = 1,4-bis[(3,5-dimethyl)-pyrazol-4-yl]benzene). MOF 2 features infinite chains of tetrahedral Zn2+ ions bridged by the linker pyrazolate groups. With the aim of developing new robust functional materials, we have begun to explore the synthesis of pyrazolate-based MOFs containing functionalized dipyrazolate ligand, H2[(Me2pyz)2biPh-NH2], containing an amine functional group on the biphenyl core.
