V and -1.67 V, respectively, in DCM), implying that pDTCz-DPmS will be a more effective ground state reducing agent. Small variations of up to 50 mV in Ered are obtained for both compounds as a function of solvent polarity. Generally, with increasing solvent polarity, a more negative Ered value is observed. Due the small electrochemical windows of THF and DMF, the impact of solvent polarity on Eox could not be determined.
