| Outline of Final Research Achievements |
Light-harvesting antenna systems in natural phototrophs are usually constructed by specific interaction of chlorophyll pigments with oligopeptides, but self-assemblies of chlorophylls are observed in the core part of main antennas of photosynthetic green bacteria, called chlorosomes. As models of chlorosomal chlorophylls, a variety of self-aggregative porphyrinoids were prepared by modifying naturally occurring chlorophylls and the semi-synthetic models were self-aggregated in several environments to give large oligomers with a controlled supramolecular structure. Such J-aggregates were developed on any substrates to afford photoactive nano-devices.
