Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) measurements for pDTCz-DPmS and 4CzIPN permitted the determination of the ground and excited state redox potentials, thermodynamic parameters that are of greatest relevance to photoredox catalysis to assess the feasibility of the single electron transfer (SET) events. Measurements were obtained in THF, DCM, DMF and MeCN;
