Wesenhagen, Philana published the artcilePhotochromism and Electrochemistry of a Dithienylcyclopentene Electroactive Polymer, SDS of cas: 219537-97-0, the publication is Langmuir (2008), 24(12), 6334-6342, database is CAplus and MEDLINE.
A bifunctional substituted dithienylcyclopentene photochromic switch bearing electropolymerisable methoxystyryl units, which enable immobilization of the photochromic unit on conducting substrates, is reported. The spectroscopic, electrochem., and photochem. properties of a monomer in solution are compared with those of the polymer formed through oxidative electropolymerization The electroactive polymer films prepared on Au, Pt, glassy C, and In Ti oxide (ITO) electrodes were characterized by cyclic voltammetry, XPS, and at. force microscopy (AFM). The thickness of the films formed is limited to several monolayer equivalent The photochromic properties and stability of the polymer films were studied by UV/visible spectroscopy, electrochem., and XPS. Although the films are electrochem. and photochem. stable, their mech. stability with respect to adhesion to the electrode is sensitive to both the solvent and the electrode material employed, with more apolar solvents, glassy C, and ITO electrodes providing good adhesion of the polymer film. The polymer film is formed consistently as a thin film and can be switched both optically and electrochem. between the open and closed state of the photochromic dithienylethene moiety.
