Cyclic voltammograms (CVs) of a 0.125 mM solution of BBR·8PF6 in MeCN containing a 0.1 M concentration of [Bu4N][PF6] electrolyte and ferrocene as an internal redox standard. In all the CVs, the current is normalized relative to the square root of the scan rate. (a) Scan rates of 0.05, 0.1, 0.2, and 0.5 V/s with a potential window that includes all accessible oxidation states of the rotaxane. (b) Scan rates of 0.5, 1, 2.5, 5.0, and 10.0 V/s over a potential window that includes only the BBR8+ and BBR4(+•) oxidation states of the rotaxane. (c) Scan rate of 50.0 V/s over a potential window that includes only the BBR8+ and BBR4(+•) oxidation states of the rotaxane. The capacitive current at 50.0 V/s was measured independently and subtracted from this CV.
