A trial separation : A dye‐sensitized nanocrystalline TiO 2 film (see scheme) is prepared in which a remarkably long‐lived (4 s) charge‐separated state can be generated. The key parameter that controls charge transfer at the dye/TiO 2 interface is shown to be the spatial separation between the cation center of the dye and the electrode surface.
