Electrochemical Studies. Redox behavior of 1 and 2 were
followed by cyclic (CV) and differential pulse voltammetry
(DPV) in the potential range from +2.0 to −2.0 V in CH3CN
(c, 100 μM) at rt and scan rate of 100 mV s−1 using 0.1 M [(n-
Bu)4N]ClO4 as a supporting electrolyte. Resulting voltammograms
for 1 and 2 are depicted in Figure 4.
