A family of polymers based on alternating bi-EDOT and pyridine units is reported. Poly(BEDOT-PyrPyr-Ph2), with a bandgap of 1.2 eV, has four electrochemically accessible colors (dark gray, burgundy, lime green, and light gray) each corresponding to a distinct redox state. In-situ conductance measurements illustrate high n-type doping conductances only thirty times less than those of the p-type doping conductances.
