Conducting Polymetallorotaxanes: Metal Ion Mediated Enhancements in Conductivity and Charge Localization

摘要

The metal-free PolyRot(1) and PolyRot(2) were produced by extracting the metal ions, and these polymers reversibly bound Zn~2+ or Cu~2+ ions in solution. The Cu~2+ dopes the films of PolyRot(2) and Poly(2), which have lower oxidation potential than those of PolyRot(1), to Produce 10~6-10~7-fold conductivity increases. In the case of PolyRot(1) and Poly(1), the rotaxane structure was Demonstrated to be key for reversible complexation of metal ions.
