(a) CVs recorded during the reductive electropolymerization of 3(PF6)4 (around 0.5 mM in CH3CN) at an ITO glass electrode by 15 potential cycles between −0.8 and −1.7 V). (b) CVs of the poly-3n+/ITO film obtained in (a) at different scan rates (20, 40, 60, 80, and 100 mV/s, respectively). (c) Linear dependence of the peak currents of the redox wave at +0.36 V in (b) as a function of scan rate. (d) CVs of poly-3n+/ITO films obtained after 15, 30, and 45 potential cycles. The scan rate is 20 mV/s. The surface coverage is 3.0 × 10−9, 5.0 × 10−9, and 8.0 × 10−9 mol/cm2, respectively.
