Porphyrins are essential pigments in biological systems. Porphyrins and chlorophylls are often self-assembled into nanoscale superstructures to perform many essential functions, such as light harvesting and electron transport. The crystal structure of the light-harvesting antenna complexes (LHC) in purple photosynthetic bacteria shows the presence of a highly symmetric wheel-like supramolecular architecture involving a large number of bacteriochlorophyll pigments. Many artificial models of light-harvesting antenna systems have been synthesized in an attempt to understand the energy transport phenomena that occur in natural light-harvesting complexes. As mimic of natural light harvesting system, we recently have designed several porphyrin-based artificial models including porphyrin dendrmers, self-assembled nano-ring, and supramolecular receptors. In this symposium, we are going to introduce recent advances in our researches related to the mimicry of natural light harvesting system. |
