Abstract

The electrode reaction of tris(2,2'-bipyridine)cobalt complex, [Co(bpy)3]3+/2+, has been investigated in 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) and 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIBF4). Diffusion of [Co(bpy)3]2+ and [Co(bpy)3]3+ was affected by the viscosity and the charge densities of the complex and the anion of ionic liquid. The large change of the electron configurations of [Co(bpy)3]2+ and [Co(bpy)3]3+ is considered to cause the slow charge transfer and large reaction entropy change.
