(a) Disk currents at 5000 rpm in hydrodynamic voltammograms of 0.13 mM HCF(II) in 0.1 M KCl (black line) in presence of 0.52 mM P(MAPTAC-co-APMA-x%) (with respect to quaternized units, icr = 1) with x% APMA content as indicated: 0% (black), 5% (red), 10% (green), 15% blue and 30% magenta (arrow indicates shift of voltammograms with increasing APMA content) and (b) disk currents normalized to limiting disk currents for hydrodynamic voltammograms of 0.13 mM HCF(II) in 0.1 M KCl in absence (black) and presence of 0.52 mM PMAPTAC (red) and PAPMA (blue) (with respect to quaternized units, icr = 1) (disk potential scanned from 0 to 0.5 V (forward scan) and back to 0 V (backward scan) vs. Ag/AgCl with ν = 5 mV/s).
