Fig. 4. CV curves of SAMs on gold: (a) SAM-3-H, (b) SAM-2-Rad, (c) SAM-3-Rad and (d) SAM-5-Rad in CH2Cl2 + 0.2 M Bu4NPF6 at different scan rates (0.05, 0.1, 0.25, 0.5, 1, 2, 3 and 4 V s–1). The color code used for SAMs is the same as that used in Scheme 1. (Blue) PTM αH; (magenta) PTM radical; (yellow) triazole ring; (green) Fc and (violet) terminal alkyne moieties.
