Preparation of Photoresponsive Charge Separation Membranes

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响应电荷分离膜，作为光合作用初始过程的模型.制备了合成二氢锌的自聚集体作为光合绿色细菌膜外触角的模型.锌二氢卟酚的光激发自组装与细菌二氢卟酚之间的能量传递是有效的，该人工体系是一个很好的天然触角功能模型和结构模型.将合成的环状四吡咯修饰在碳糊电极上。在电子给体和受体分子存在下，电极辐照后发生了分子内电子转移.天线模型（2）和电荷分离模型（3）的组合诱导了光合作用初始过程的人工模型的制备。

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.
