The energies of the HOMO and LUMO of 4tCzPz, 4CzPz, and 4αCbPz were inferred from cyclic voltammetry (CV) and differential pulse voltammetry (DPV) measurements in DCM with tetrabutylammonium hexafluorophosphate, [ n Bu4N]PF6, as the supporting electrolyte (Figure ). The CV traces of 4tCzPz and 4CzPz show two pseudo-reversible oxidation waves with Eox = 0.76 V/1.00 V and Eox = 1.12 V/1.25 V (obtained from the maximum in the DPV), respectively. These oxidation waves reflect oxidation of two of the donor groups, behavior that has been observed in the literature. 4αCbPz shows a single irreversible oxidation wave at Eox = 1.38 V (obtained from the maximum in the ).
