| Research Abstract |
In order for light energy conversion to mimic natural photosynthetic system, we have developed the photoinduced electron transport system in vesicles, in which an electron is transferred with the aid of light energy in the energetically uphill direction across lipid bilayer membranes. To enhance the efficiency of the system, design and syntheses of novel sensitizers and optimization of various reaction conditions were carried out. Moreover, a novel hydrogen generation system using electron donors capable of undergoing reversible redox cycles was constructed by linking the electron transport system with a colloidal platinum catalyst or Pt(II) complexes acting as a molecular catalyst.
