In the initial stage of photosynthesis, solar energy is harvested in the antenna and successively charge separation occurs in the reaction center. We prepared photoresponsive charge separation membrane on the solid surface as a model for the initial process of photosynthesis.1. Self-aggregates of synthetic zinc chlorin was prepared as a model for extramembranous antennae of photosynthetic green bacteria.2. Energy transfer from photoexcited self-assembly of the zinc chlorin to a bacteriochlorin occurred efficiently and the artificial system was a good functional model for natural antennae as well as a good structural model.3. Synthetic cyclic tetrapyrroles were modified on the carbon pasted electrode. Upon the irradiation of the electrode, intramolecular electron transfer was occurred in the presence of electron donor and acceptor molecules.4. Combination of the antenna (2) and charge separation models (3) induces the preparation of the artificial model of the initial process of photosynthesis.

在光合作用的初始阶段，太阳能在天线中被收集，随后在反应中心发生电荷分离。我们在固体表面制备了光敏电荷分离膜，作为光合作用初始过程的模型。制备了人工合成的氯化锌自聚体作为光合绿细菌膜外触角的模型。该人工体系不仅是天然天线良好的功能模型，也是良好的结构模型，有效地实现了锌氯向细菌氯的光激发自组装。将合成的环状四氢吡咯修饰在碳糊电极上。在电子给体分子和受体分子存在的情况下，电极辐照后发生了分子内的电子转移。天线(2)和电荷分离模型(3)的结合导致了光合作用初始过程的人工模型的制备。
