Functional field‐effect transistors (FETs) have received increasing attention in recent years. Herein, it is demonstrated that the incorporation of hydrophilic tetraethylene glycol (TEEG) chains into the diketopyrrolopyrrole (DPP)‐based semiconducting polymer (PDPP3T1) can facilitate the formation o...
