| Abstract: | Electrochemical quartz crystal microbalance measurements are reported for redox switching of thin films of three macromolecule-metal complexes: poly(vinylferrocene) (PVF), 10% osmium-functionalized poly(vinylpyridine) (Os-PVP), and 10% osmium functionalized poly(vinylpyridine-co-styrene) (Os-PVP-co-PS). The data provide insight into the ion and solvent transfer processes associated with electron transfer between the electrode and the electroactive film. Four important parameters are identified: electrolyte composition, (co)polymer composition, prior film history and experimental time scale. |
