摘要

Solid state electrochromic cells of the configuration SnO2 Glass; poly(AMPS) + HV(2+) + NaPF6; Nafion 117; poly(AMPS) + CeC13 + NaPF6; SnO2 Glass were prepared. Upon subjecting the Heptyl Viologen (HV(2+)) working electrode compartment to a cathodic scan, two distinct reduction peaks were observed at respectively -1.74 and -1.90V versus the Cec13/Sn02 reference counter electrode. This corresponded to the formation of respectively, the radical and diradical cation species of HV(2+). This electrochromic cell was found to be highly electrochemically reversible as monitored by a He/Ne laser beam (583nm) transmitted through the bulk of this semitransparent thin film solid-state cell. Cells were also prepared using n-TiO2 as the working electrode in contact with the HV(2+) compartment. A progressive trend to more negative n-TiO2 flat band potentials (V sub FB) was observed between the initially prepared cell and the first and second electrochemically formed HV(2+) radical cation species.
