Abstract

Iron 5-(3-thienyl)-10,15,20-triethylporphyrin was electropolymerized in supercritical carbon dioxide (scCO2) to yield the corresponding conductive polymer film. The film was analyzed by scanning electron microscopy, laser microscopy and AFM. It was revealed that the thiophene-porphyrin film synthesized in scCO2 was more dense and smoother than those synthesized in dichloromethane. The electrocatalyst was applied to a superoxide anion radical sensor, and its detection sensitivity was drastically increased.
