3,4-Ethylenedioxythiophene-Pyridine-Based Polymers: Redox or n-Type Electronic Conductivity?

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 measure...

Summary: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.
