• ), IR and UV–vis spectroscopy, as well as 29Si and 13C CP-MAS NMR techniques. The material features a high inner surface area and a highly ordered two-dimensional hexagonal pore structure. The fluorescence properties of the organic chromophore can be tuned via complexation of its carbonyl group with

• nanostructure. It was reported that cathodic photocurrents were obtained at a nanocrystalline TiO2 film electrode due to oxygen reduction in alkaline solutions [7]. Visible light sensitization of TiO2 by surface complexation with [Fe(CN)6]4− has also been reported [8]. In such a case it was suggested that the
