Heterosupramolecular assemblies based on modified transparent nanostructured TiO2 (anatase) membranes are described. Exposure of these heterosupramolecular assemblies to visible light causes them to turn blue. Furthermore, if a negative potential is applied to the nanostructured TiO2 membrane this blue color persists for hours. Because only those areas which have been irradiated are blue, and because the lifetime of the blue colored state depends on the potential applied to the nanostructured TiO2 membrane, applications are foreseen for these photoelectrochromic materials.
