Effects of overoxidation on tris-(5-amino-1,10 phenanthroline) ruthenium (II) electropolymerized thin films
Author(s): Sophie Turner and Kenneth Brown
Abstract: Electropolymerization is a widely used technique to develop polymer thin films, yet research is limited on the effects of deliberate overoxidation of these films. Tris-(5-amino-1,10 phenanthroline)ruthenium (II) was used to produce metallopolymer films on glassy carbon electrodes (GCE). During electropolymerization, the potential window of the cyclic voltammetric (CV) scan was extended beyond 2.00 V to observe the effects of overoxidation on the film. During characterization of the films, when the voltage was extended beyond 2.30 V, significant reduction in the cathodic peak current occurred due to the production of insulating domains within the polymer film and partial delamination of the film from the GCE. When any delamination of the film occurs, the functionality of the electrode is diminished for practical applications. The maximum potential voltage that a film is exposed to is crucial to the stability of the film and should be monitored during the development and testing of sensors.
