Abstract:
Electrochemical one-electron reduction of the extended viologen dication 1^2+ proceeds reversibly at -0.64 V (vs. Ag|AgCl electrode) to yield the red cation radical 1^+. , which readily produces a dark blue dimer hindering the observation of a second one-electron reduction of 1^+.. Conventional electrochemical methods suggest that the only second reduction step occurs at -1.4 V.Fast cyclic voltammetry at scan rates up to kV/s and voltammetry at micromolar concentrations eliminate the coupled bimolecular chemical reactions and permit the determination of the reduction potential of the cation radical 1^+. .
