Abstract

Magnetic field effects (MFEs) on photoelectrochemical reaction of a porphyrin-viologen linked compound with six methylene group (ZnP(n)V(n=6)) were examined in an ionic liquid ([BMIM][BF4]) using two-electrode cell. A stable anodic photocurrent is produced by irradiating ZnP(6)V in [BMIM][BF4] with visible light, and the photocurrent clearly increased in the presence of a magnetic field. The MFEs are explained by radical pair mechanism. The magnitude of the MFEs is larger than those in electrodes modified with ZnP(n)V(n=4,6,8) as Langmuir-Blodgett films. The results are most likely ascribed to the properties of [BMIM][BF₄].
