Cyclic_Voltammetry.zip

Cyclic voltammetry (CV) measurements were performed in a one-chamber, three-electrode cell using a PGSTAT302 potentiostat. A 2 mm2 Pt electrode from BASi was used as the working electrode with a platinum wire serving as the counter electrode relative to an Ag/AgCl (nonaqueous) reference electrode submerged in either 0.01 M AgNO3/0.1 M n-Bu4PF6 in anhydrous acetonitrile or 0.01 M AgNO3/0.1 M n-Bu4Cl in anhydrous acetonitrile (MeCN). Measurements were taken in either 0.1 M n-Bu4PF6 (in MeCN) electrolyte solution or 0.1 M n-Bu4Cl (in MeCN) at various scan rates from 10 mV/s to 250 mV/s. Potentials relative to the Ag/Ag+ couple to which the Fc/Fc+ couple was measured to be 262 mV (Figure S17). The potential for ferrocene redox is -4.8 eV relative to vacuum. Energy levels of the highest occupied molecular orbital (HOMO) were calculated according to the equations: HOMO = -e(Eox+ 4.64) (eV), where Eox is the onset oxidation potential vs Ag/AgCl.
