CV and OECT performance. Oxidation onset potential E_ox,H2O measured against Ag/AgCl in 0.1 M NaCl in H₂O from −0.4 to 0.6 V and E_ox,AcN measured against Fc/Fc⁺ in 0.1 M NBu₄PF₆ in AcN from −0.8 to 0.8 V; threshold voltage V_th obtained from OECT transfer curves; maximum value of the product of hole mobility and volumetric capacitance, [μC*]_max, obtained from OECT transfer curves; maximum volumetric capacitance determined through EIS; maximum hole mobility μ_max obtained by dividing [μC*] by C*. Values within brackets denote the corresponding gate potential for each value; the mean and min–max error of the values extracted from two devices are given.
