A new path to highly conducting n-doped π-conjugated polymers

Summary: This research introduces a facilely synthesized highly conductive n-type polymer with breakthrough conductivity and solution processability. By improving doping efficiency, the polymer achieves a doping level of almost 0.9 charges per repeating unit. Further investigations demonstrate the coherent charge-transport properties and existence of metallic state. The benchmark performances in electrochemical transistors and thermoelectric generators are also demonstrated.
