a Chemical structure of 2DPP-OD-TEG polymer. b Measurement configuration used for OECT measurements. Typical n-type (c) and p-type (d) OECT transfer characteristics of 2DPP-OD-TEG OECTs measured in 0.1 M aqueous NaCl. Transfer characteristics were measured by scanning the gate voltage at a scan rate of 20 mV/s from 0 to 1.2 V with the drain-source bias voltage (VDS) set to 0.4 V for n-type and from 0 to −1.2 V at VDS = −0.4 V for p-type electrochemical doping.
