Abstract
The kinetic study of interfacial electron transfer in sensitized nanocrystalline semiconductor is
essential to the design of molecular devices performing specific light induced functions in a microheterogeneous
environment. A series of molecular assemblies performing direct and remote charge injection to the
semiconductor have been discussed in the context of artificial photosynthesis. A particular attention in this
article has been paid to the factors that control the interfacial electron transfer processes in nanocrystalline
TiO2 films sensitized with mononuclear and polynuclear transition metal complexes.
