Integration of the signals obtained in differential pulse voltammetry (DPV) measurements showed that the three redox process of BT-DCAF correspond to one-electron reduction/oxidation electrochemical reactions (Figure ). In comparison, BT-MCAF shows two irreversible one-electron reductions and one quasireversible two-electron reduction/oxidation (Figure ). The molecular symmetry of BT-DCAF appears to be important to achieve electron delocalization (Figure ) and full reversibility upon electrochemical reduction. The redox potentials (E1/2) of BT-MCAF and BT-DCAF determined experimentally by CV and DPV techniques are in good agreement between the two electrochemical techniques (variations from 0.01 to 0.04 V).
