| Outline of Final Research Achievements |
The utilization of the sun light is effective method to solve severe energy and environmental problem that we currently face. The concentration of the sun energy is a key process in order to use energy of the sun. In this study, I succeeded in arranging a lot of antenna pigments (porphyrin) precisely by using dendrimers with rigid conjugated chains. As a result, I succeeded in the construction of the antenna molecules which have strong absorption throughout the visible light region. I proved nearly quantitative energy transfer from the peripheral porphyrins to a central porphyrin by means of spectroscopic measurements. In addition, I developed a novel synthetic technique to integrate a large number of dendrimer effectively. I can construct a huge sun light-harvesting system by accumulating a lot of antenna molecules by using this technique.
