Polymeric mixed ionic–electronic conductors based on quinoid–azaisoindigo for n-type organic electrochemical transistors

A novel electron-deficient quinoid–azaisoindigo building block was synthesized for a series of alternative D–A conjugated polymers, applied as the channel layer in n-type OECTs, achieving a mix conducting figure of merit μC * of 0.53 F V −1 cm −1 s −1 .
