Magnetic Field Effects on Photoelectrochemical Responses of Modified Electrodes with Porphyrin-Viologen Linked Compound as Langmuir Blodgett Film

Modified electrodes were fabricated by depositing a monolayer containing porphyrin-viologen linked compound on ITO electrodes by Langmuir-Blodgett method. Visible light irradiation on the modified electrodes afforded stable anodic photocurrents. The photocurrents clearly increased in the presence of...

Zusammenfassung:Modified electrodes were fabricated by depositing a monolayer containing porphyrin-viologen linked compound on ITO electrodes by Langmuir-Blodgett method. Visible light irradiation on the modified electrodes afforded stable anodic photocurrents. The photocurrents clearly increased in the presence of magnetic fields. The magnetic field effects on photocurrents, as observed for the first time, are ascribed to the contribution of triplet radical pairs.
