Due to its highly-reversible and extremely stable nature, thianthrene has been targeted as an attractive functionality for conducting polymer actuators based on molecular motion. A series of conducting polymers have been prepared by electrochemical deposition of monomers that incorporate thiophene-based electroactive units and thianthrene moieties. As polymer-modified electrodes, the thin films have been studied by a variety of techniques including electrochemistry, spectroelectrochemistry, and in situ conductivity. Additionally, free-standing films have been prepared under a variety of conditions and the material properties of the resulting films have been investigated. Mechanical, bulk conductivity, and actuation properties of the films have been measured and will be reported herein.
