In article number 2000270, Alberto Salleo, Yoeri van de Burgt, and co‐workers add small‐molecule amines to PEDOT:PSS in solution to fabricate high‐performance enhancement‐mode organic electrochemical transistors. Small‐molecule amines efficiently de‐dope PEDOT:PSS, shifting the transistor operation from depletion to enhancement mode without degrading the device performance. The effects of the de‐dopant on the device performance, electronic structure, and microstructure are investigated.
