A novel approach to the attachment of molecular dyes to nanocrystalline TiO 2 electrodes (see Figure) is reported. Cyclodextrin encapsulation of an organic dye is shown to result in strong binding to the metal oxide electrode. The encapsulation furthermore results in a well‐defined spatial separation of the organic dye from the electrode surface, allowing the photogeneration of a long‐lived charge‐separated state.
