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.
