Fig. 10. Cyclic voltammetry and Raman spectroscopy of compound 1a.

a Cyclic voltammetry of 1a versus Ag⁺|AgCl in the solid state. 5 mg of the target material were dispersed in 500 µL of a 4% PVA solution in water and vigorously sonicated, then 125 µL of a 4% BORAX solution in water were added, forming a gel that was then applied onto a glassy carbon electrode (3 mm diameter). The scan rate was 50 mV s^–1 in 1 M KCl; b in-situ Raman spectroscopy measurements of the 1a, showing the pristine clathrate (red) after the reduction (blue) and after re-oxidation (yellow). The dashed lines highlight the new peaks of the reduced compound.
