procedure described in [5]. The H NMR spectra were
recorded in CDCl3 on a Jeol JNM-ECX400 spectrom-
eter (400.1 MHz). The electrochemical redox poten-
tials were measured using a three-electrode cell and
an IPC Pro-M digital potentiostat/galvanostat (Vol’ta,
Russia). A stationary platinum electrode with a diam-
eter of 2 mm was used as working electrode, a satu-
rated AgCl electrode was used as reference, and
a Pt electrode was used as auxiliary. The cells were
purged with dry argon to remove oxygen. The sub-
strate concentration was 10–3 M. After recording each
curve, the Pt electrode was thoroughly cleaned.
