Electron self-exchange dynamics of hexacyanoferrate in redox polyether hybrid molten salts containing polyether-tailed counterions

Article Abstract:

A highly viscous room-temperature redox polyether hybrid melt was prepared by combining the hexacyanoferrate(III) with a quaternary ammonium countercation consisting of triethylammonium connected to a poly(ethylene glycol) methyl ether. The microelectrode voltammetry and potential step chronoamperometry in the undiluted melt give an apparent diffusion coefficient of D(sub APP) = 2.5 x 10(super -10) cm(super 2)/s at 20 degree Centigrade.

Ion atmosphere relaxation controlled electron transfers in cobaltocenium polyether molten salts

Article Abstract:

A room-temperature redox molten salt for study of electron transfers in semisolid media, based in combining bis(cyclopentadienyl) cobalt with oligomeric polyether counterions is reported. The results support the generality of the proposed model of ionic atmosphere relaxation control of electron transfers in ionically conductive, semisolid materials.

Solid-state voltammetry in a polyether-tailed Co tris(bipyridine) molten salt: ion pairing effects

Article Abstract:

The study describes experiments exploring the role of the redox-inactive counterion in hybrid redox polyether molten salts. As these materials are undiluted, they intrinsically contain "solvent-separated ion pairs", where the "solvent" is the polyether tail attached to the redox moiety.
