Synthesis and Structures of New Three-Dimensional Copper Metal-Organic Frameworks
Metal-organic frameworks (MOFs) are crystalline materials with metal ions covalently bonded to organic ligands. The ligands act as spacers often creating a porous structure with very high pore volume and surface area. MOFs are known for their robust structures, high porosity, and different chemical...

| Summary: | Metal-organic frameworks (MOFs) are crystalline materials with metal ions covalently bonded to organic ligands. The ligands act as spacers often creating a porous structure with very high pore volume and surface area. MOFs are known for their robust structures, high porosity, and different chemical functionalities and are considered for applications in adsorptions, separations, catalysis and gas storage. This work focuses on the synthesis of new MOFs using copper compounds. Different types of carboxylate ligands were used for the synthesis. Two new copper-organic frameworks, [Cu3(pyz)(btc)] (1), and [(Cu3(btc))•xH2O] (2) (btc= benzene-1,3,5-tricarboxylate, pyz= pyrazine) have been synthesized using hydro/solvothermal methods and have been characterized using X-ray diffraction, IR, TGA, fluorescence and CHN analysis. |
