High‐Performance Ambipolar Organic Electrochemical Transistors Based on Diketopyrrolopyrrole‐Dialkoxybithiazole Conjugated Polymers for Single‐component Inverters

Advanced Science, EarlyView.
Two donor‐acceptor conjugated polymers, incorporating diketopyrrolopyrrole (DPP) and dialkoxybithiazole (2Tz) units with ethylene glycol (EG) side chains, exhibit relatively balanced ambipolar organic electrochemical transistor (OECT) performance. This ambipolarity enables the realization of single‐component complementary inverters capable of ternary ...
