Electron transfer at dye-semiconductor interfaces is a critical event in bio/organic electronics, solar energy conversion, sensing, and of particular importance to this symposium, dye-sensitized photoelectrosynthesis. At the interfaces in these devices, the goal is to maximize the rate of electron transfer in one direction and suppress it in the reverse direction. In this presentation we introduce self-assembled bilayers of a molecular bridge, metal ion, and a phosphorescent dye molecules on nanocrystalline metal oxide films as an effective strategy for modulating electron transfer dynamics at the dye-semiconductor interface. The nature of the bridging molecule and the metal ion can have a profound impact on the electron transfer rates, mechanism, and efficiency of both forward and back electron transfer processes.<br/>
