We describe the charge transfer interactions between photoexcited CdS nanorods and a mononuclear water oxidation catalyst derived from the [Ru(bpy)(tpy)Cl]+ parent structure. Upon excitation, hole transfer from CdS oxidizes the catalyst (Ru2+→Ru3+) on a 100 ps - 1 ns timescale. This is followed by 10 - 100 ns electron transfer ...
