| Research Abstract |
The photoelectrochemical properties of semiconducting polymers thin films on ITO electrodes were investigated in aqueous media. Photoirradiation of the p-type semiconducting polymer-coated electrode resulted in cathodic photocurrents in the presence of methyl benzoylformate, whereas the n-type semiconducting polymer-coated electrode generated stable anodic photocurrents in the presence of2-mercaptoethanol. Formation of the bilayer film of the p-and n-type semiconducting polymers exhibited opposite photoelectrode characteristics at the polymer/water interface, and introduction of poly(3-hexylthiophene) layer improved photoelectrochemical response of phthalocyanine-modified electrode.
