Unusually fast electron and anion transport processes observed in the oxidation of "electrochemically open" microcrystalline [{M(bipy)2}(mu-L)](PF6)2 complexes (M,M'=Ru, Os; bipy+2,) at a solid-electrode-aqueous electrolyte interface. dianion at a solid-electrode-aqueous electrolyte interface

Article Abstract:

A new study investigates the oxidation of dinuclear ruthenium and osmium metal complexes of the type [{M(bipy)2}(mu-L)](PF6)n, where L=1,4-dihydroxy-2,5-bis(pyrazol-1'-yl)benzene.

Protonation effects on the structure and homogeneous charge transport dynamics of solid osmium bis(bispyridyl)tetrazine chloride films

Article Abstract:

Mechanically attached solid state films of [Os(bpy)2-4-tet-Cl]ClO4, where bpy is 2,2'-bipyridyl and 4-tet is 3,6-bis(4-pyridyl)-1,2,4,5-tetrazine is formed on platinum microelectrodes. Scanning electron microscopy reveals that films exist as an amorphous array of microscopically small particles.

Redox properties of ground and electronically excited states: (Ru(bpy)2Qbpy)2+ monolayers

Article Abstract:

A study was conducted to analyze the redox characteristics of ground and electronically excited states of the dense monolayers of (Ru(bpy)2Qbpy)2+. The heterogeneous electron-transfer rate constant was determined using chronoamperometry conducted on a microsecond time scale. Experimental results indicated that the electron-transfer rate constant was larger for the excited state than for the grounds-tate bpy anion radical bpy-.
