Figure 2.
Cyclic voltammetry of 1 (upper panel, 1 mM) and 2 (lower panel, 1 mM). Electrolyte: 0.1 M TBAPF6 in MeCN, scan rate: 100 mV/s, electrode: highly oriented pyrolytic graphite. The initial potential of the voltammogram of 1 (upper panel) is at ca. −0.30 V, and the initial potential of the voltammogram of 2 (lower panel) is at ca. −1.2 V.
