A new n‐dopable polyketone, poly[(5‐(2,5‐dihexyl‐4‐(thiophen‐2‐yl)phenyl)thiophen‐2‐yl)(4‐ketophenyl)methanone] (PTK), is synthesized via Friedel–Crafts acylation. Though insulating in the neutral state, PTK becomes conductive upon electrochemical reduction. The stable, two‐electron, fully reversible reduction is probed spectroelectrochemically and via in‐situ conductivity measurements.
