Poly(diketopyrrolopyrrole) (PDPP)-based π-conjugated polyelectrolytes (CPEs), facilitating either electron or hole transport for applications in organic electrochemical transistors (OECTs), were synthesized. By equipping each polymer main-chain with neutral, anionic, or cationic side chains, the resulting series of polymers encompasses all possible combinations of negative, positive, and neutral side-chain ionic charges in combination with in situ-generated holes […]
