Figure 4.
Cyclic voltammograms (top) and differential pulse voltammograms (DPV, bottom) of biipo (black, concentration <1 mm due to low solubility in acetonitrile) and Rubiipo (orange, 1 mm) in acetonitrile solution referenced vs. the ferrocene/ferricenium (Fc/Fc+) couple. The current values of the DPV are normalized. Conditions: scan rate of 100 mV s−1, [Bu4N][PF6] (0.1 m) as supporting electrolyte.
