Abstract:Photoactive anodes consisting of Ru(bpy)3 type photosensitizer 1 and molecular catalysts 2 and 3 on nanostructured TiO2 have been assembled in functional devices for successful light driven water splitting. From their performance measurements we found that the photoanode TiO2(1 + 3) in which the molecular ruthenium catalyst and the phosphonate anchoring group are linked by a flexible -CH2CH2CH2- chain showed a significantly higher photocurrent density than the photoanode TiO2(1 + 2) with only -CH2- linkage. The possible reasons for the different water splitting performance of otherwise identical devices are discussed.
