Polypyrrole-phthalocyanine

Polypyrrole films incorporating sulfonated phthalocyanines have been synthesized on Pt and indium-tin-oxide electrodes from aqueous solution. We report on the spectroelectrochemical and stability properties of the films incorporating tetra- and mono-sulfonated cobalt-phthalocyanine and tetra-sulfona...

Description
Summary:Polypyrrole films incorporating sulfonated phthalocyanines have been synthesized on Pt and indium-tin-oxide electrodes from aqueous solution. We report on the spectroelectrochemical and stability properties of the films incorporating tetra- and mono-sulfonated cobalt-phthalocyanine and tetra-sulfonated metal-free phthalocyanine. The films are strongly electrochromic and have four distinctly different color stages in the potential range 1.2 V to −1.6 V versus SCE. The films are more stable as electrodes than polypyrrole complexed with inorganic counterions and show a higher degree of crystallinity.
