Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) measurements were carried out in dichloromethane (DCM) to experimentally ascertain the HOMO and LUMO levels (Figure ). The electrochemical data is compiled in Table . The reduction waves of ). The corresponding electrochemical gap for 3DPA-DikTA is 2.12 eV and for 3TPA-DikTA is 2.29 eV, both significantly smaller than that of DiKTa at 3.12 eV.
