Spectroscopic data of self-assembled layer. (a) SEIRA spectra collected on the first CV cycle at the potential values indicated, where the background spectrum was collected at −0.1 V vs Ag/AgCl in 0.1 M NaClO₄ in the absence of 200 μM C18-Fc. (b) Identical spectra as shown in as a, however, the background spectrum was collected at −0.1 V vs Ag/AgCl in 0.1 M NaClO₄ in the presence of 200 μM C18-Fc. (c) The initial, first CV cycle collected upon the addition of 200 μM C18-Fc in tandem with a and b at 2 mV s^–1 from −0.1 V vs Ag/AgCl. The anodic integrated charge is shown. (d) Integrated band intensity (IBI) taken from b of the peak centered at 1110 cm^–1. (e) IBI taken from b of the peak centered at 1626 cm^–1. (f) IBI taken from b of the peak centered at 3100 cm^–1. (g) IBI taken from b of the peak centered at 1532 cm^–1. (h) IBI taken from b of the peak centered at 2963, 2925, and 2853 cm^–1.
