✦ Synopsis
Abe&act-A photoresponsive electrode was prepared by coating a N&on film on an indium tin oxide (ITO) electrode incorporating the Ru(bpy)$+ complex in the fihn. A photocurrent was induced at the coated electrode dipped in an aqueous electrolyte in the presence of oxygen. The action spectrum showed that the photocurrent is based on the reaction between 0, and the excited Ru complex. Viologen molecules present as a solute or as the second 6lm on the top of the Nafion[Ru(bpy)i+] film increase the fduc$ photocurrent by about a factor of two by working as a mediator between the excited Ru(bpy)$+
