【摘要】 <正>吡啶钌配合物因在光、电、磁和催化等领域显示出潜在的应用价值而受到广泛关注[1-5],含氧桥羧酸桥双核或三核钌配合物具有多个配位点,既能与金属配位又能与非金属配位,适合进行表面配位研究[6,7],因此,含氮杂环的氧桥羧酸桥多核钌配合物具有更广的应用前景。
【Abstract】 Using RuCl3.3H2O,H2O,CH3COOH,CH3CH2OH,NH4PF6 and 2,2’-bipyridine as starting materials,[Ru2(μ-O)(μ-CH3COO)2(2,2’-bipyridine)2L2](PF6)2 was synthesized by one-pot method.Its structure was characterized by 1H NMR,IR,MS and elemental analysis.Electronic absorption spectra and redox property were investigated by UV-vis and CV,respectively.The complex show a strong visible absorption band around 600 nm and the maximum absorption wavelength was affected slightly by the monodentate ligand L.The complex [Ru2(μ-O)(μ-CH3COO)2(2,2’-bipyridine)2(CH3CN)2](PF6)2 in acetonitrile show a quasi-reversible Ru2(Ⅲ,Ⅲ)/Ru2(Ⅲ,Ⅳ) redox wave around +1.388 to +1.049V versus Ag/AgCl and an irreversible Ru2(Ⅱ,Ⅲ)/Ru2(Ⅲ,Ⅲ) wave around +0.087 to-0.420V.The complex can be utilized to sensitize TiO2 in decomposing methyl orange under visible light.
