摘要：

The redox thermodynamics of thin films ( less than 200 nm) of linear polyvinylferrocene (LPVF) deposited by spincoating on polished electrode substrates have been studied in tetra-n-butylammonium perchlorate plus acetonitrile solutions. Three distinct regions of thermodynamic behavior were revealed through analysis of Nernst plots (E vs. log(c//F//c plus /c//F//c**0)) constructed from controlled potential coulometric data. For films which were 0-3% oxidized, super-Nernstian slopes with values dependent upon electrolyte concentration were attributed to Donnan equilibrium contributions to the electrode potential. This form of LPVF thus appears to function as a simple anion exchanger.
