Study in the development of light energy conversion system using lipid bilayer membranes

为了模拟自然光合系统的光能转换，我们开发了囊泡中的光诱导电子传递系统，其中电子在光能的帮助下沿能量向上的方向穿过脂质双层膜进行传递。为了提高系统的效率，进行了新型敏化剂的设计和合成以及各种反应条件的优化。此外，一种新的氢生成系统，使用能够进行可逆的氧化还原循环的电子供体，通过连接的电子传输系统与胶体铂催化剂或Pt（II）配合物作为分子催化剂。

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.
