^aMeasurements were carried out in degassed 0.1 M NaCl aqueous solution vs Ag/AgCl, * observation of an additional reduction peak at >1.1 V.

^bThe detailed EIS analysis is presented in Figure S26; the electrode area is 3.48 × 10^–3 cm² with an offset voltage of −0.6 V vs Ag/AgCl. The capacitance values here represent the effective capacitance at 1 Hz.

^cThe capacitance values used to extract C* are from fits of EIS data to a Randle’s circuit (R_s(R_p∥C).

^dElectron mobility extracted from OFET (output and transfer curves are presented in the Figure S29).

^eElectron mobility extracted from OECT as previously reported.^40,42

^fDevice dimensions W = 100 μm, L = 10 μm with the indicated thickness; transconductance is normalized by thickness. OECTs were fabricated and characterized as previously reported.⁷
