Synthesis,Structure and Properties of Ruthenium Polypyridyl Metalloligand Based Metal-Organic FrameworksPolapally, Mamatha 01 July 2017 (has links)
Metal-organic frameworks (MOFs) have been extensively studied because of their amazing applications in gas storage, purification, photocatalysis, chemical sensing, and imaging techniques. Ruthenium polypyridyl complexes have been broadly considered as photosensitizers for the conversion of solar energy and photoelectronic materials. With this aspect, we have synthesized three new ruthenium polypyridyl based MOFs ([Ru(H2bpc)Cu(bpc)(Hbpc)2(H2O)]·5H2O (1), [Ru(H2bpc)(Fe(bpc)(Hbpc)2(H2O)2]·6H2O (2) and [Ru(H2bpc)Ni(bpc)(Hbpc)2(H2O)2]·6H2O (3)) from ruthenium(III) chloride, bpc (2,2’- bipyridine-4,4’-dicarboxylic acid) ligand, and 3d M(II) metal ions (M(II)= Cu(II), Fe(II), Ni(II)). These MOFs were synthesized under hydro or solvothermal conditions by using water, ethanol or methanol as solvents. The crystal structures of the new compounds contains zigzag chains of [Ru(bpc)3]n- complex ions linked by Cu, Fe or Ni complex ions individually. Above synthesized crystal structures were characterizing by single-crystal Xray and powder X-ray diffraction strategies, UV-vis and IR spectroscopy. Thermal properties were determining by thermogravimetric analysis. Magnetic properties were also studied.
