説明:

Molecular doping has enabled control of electronic properties in semiconducting polymers for charge-transport studies and device applications. However, conventional dopant anions are mostly organic monovalent species designed for stable charge compensation. Here, we introduce polyoxometalates as multivalent oxide-cluster dopant ions into semicrystalline polymer semiconductors. Films doped with size-compatible divalent [W6O19]2- retain lamellar order, exhibit conductivity above 200 S cm-1, and show a Hall response, indicating partially coherent carrier transport. Compared with inert-anion-doped films, \pomanion-doped films show enhanced anodic response in the oxygen-evolution region, demonstrating functional multivalent-ion doping for electronic and electrocatalytic polymer semiconductor films.
