Self-assembly governed supramolecular construction of donor-acceptor nanostructures capable of mimicking biological functions is one of the fastest growing areas of research. The potential application of these to the design of molecular systems lies in self-replication, light energy harvesting and nanotechnology. Mimicking the primary events of the reaction centers of photosynthetic bacteria is an important area of research since it directly involves harvesting solar energy. The present tutorial talk will focus on the design and photoinduced electron transfer reactions in supramolecular donor-acceptor nanostructures composed of ferrocene, porphyrin, fullerene and carbon nanotubes. Utilization of metal-ligand axial coordination, crown ether-ammonium cation, hydrogen bonding involving complimentary base-pairing, pi-pi interactions, and a combination of one or more of these binding approaches in the construction of the nanostructures will be discussed. Results of photoinduced charge stabilization, as applicable for light energy harvesting, in the novel supramolecular systems will be shown. Finally, results of the photoelectrochemical cells for light energy conversion build by using some of these supramolecular nanostructures will be presented.
