• Syntheses of Homochiral Multinuclear Ru Complexes Based on Oligomeric Bibenzimidazoles

  日期：2007.8.1

  The homochiral multinuclear Ru complexes of the oligomeric bibenzimidazoles were synthesized using Lambda-[Ru(bpy)(2)(PY)(2)][(-)-O,O-dibenzoyl-L-tartrate]-12H(2)O as an enantiornerically pure building block. The complexations proceed with the retention of configuration to provide well-defined mononuclear, dinuclear, tetranuclear, and octanuclear Ru complexes successfully. The optical purity and the absolute configurations of the complexes were determined by NMR and circular dichroism spectrometry. The rare X-ray structure of a tetranuclear complex Lambda(4)[(Ru(bpy)(2))(4)(bis(BiBzlm))](PF6)(4) was resolved, The crystallographic analysis reveals that all the four Ru centers have A octahedral configurations, with a Ru-Ru separation of 5.509 angstrom across the bridging bibenzimidazole ligand, which maintains near coplanarity. The UV-vis spectroscopic and electrochemical properties of the homochiral multinuclear assemblies were studied, indicating weak electronic communications between the metal centers.
• Ruthenium(II) 2,2′-Bibenzimidazole Complex as a Second-Sphere Receptor for Anions Interaction and Colorimeter

  A ruthenium(II) complex [Ru(bpy)(2)(H(2)bbim)](PF6)(2) (1) as anions receptor has been exploited, where Ru(II)-bpy moiety acts as a chromophore and the H2bbim ligand as an anion binding site. A systematic study suggests that 1 interacts with the Cl-, Br-, I-, NO3-, HSO4, and H2PO4- anions via the formation of hydrogen bonds. Whereas 1 undergoes a stepwise process with the addition of F- and OAc- anions: formation of the monodeprotonated complex [Ru(bpy)(2)(Hbbim)] with a low anion concentration, followed by the double-deprotonated complex (Ru(bpy)(2)(bbim)], in the presence of a high anion concentration. These stepwise processes concomitant with the changes of vivid colors from yellow to orange brown and then to violet can be used for probing the F- and OAc- anions by naked eye. The deprotonation processes are not only determined by the basicity of the anion but also related to the strength of hydrogen bonding, as well as the stability of the formed compounds. Moreover, a double-deprotonated complex [Ru(bpy)(2)(bbim)] center dot CH3OH center dot H2O (3) has been synthesized, and the structural changes induced by the deprotonation has also been investigated. In addition, complexes [Ru(bpy)(2)(HbbiM)](2)(HOAc)(3)Cl-2 center dot 12H(2)O (2), [Ru(bpy)(2)(Hbbim)](HCCl3CO2)(CCl3CO2) center dot 2H(2)O (4), and [Ru(bpy)(2)-(H(2)bbim)](CF3CO2)(2)center dot 4H(2)O (5) have been synthesized to observe the second sphere coordination between the Ru(II)-H(2)bbim moiety and carboxylate groups via hydrogen bonds in the solid state.
