In the artificial leaf, one of the artificial photosynthesis systems, reverse reaction does not happen due to its two-dimensional separation of the redox reactions. The research project has a aim to design artificial organic leaves system for photocatalytic water splitting using only visible light based on our previous study of polymer film type organophotocatalyis of volatile molecules oxidation.We have succeeded the layering of p-and n-type organic semiconductors on the precisely synthesized block copolymer membrane and investigated its photoelectrochemical behaviors as follows. 1) The optimized temperature of the substances transport in the hydrophilic channel was found to be relatively higher than the room temperature. 2) The temperature dependent photooxidation rate was evaluated for the p-n junction. Furthermore, we have submitted new concept of the one-path flow reactor of organophotocatalyst where the optimized absorbance of each layer was evaluated for the first time.

在人工光合作用系统之一的人工叶片中，由于氧化还原反应的二维分离，不会发生逆反应。 本研究项目的目标是在我们之前对挥发性分子氧化的聚合物膜型有机光催化研究的基础上，设计仅使用可见光的人工有机叶子系统。我们成功地在精确合成的嵌段共聚物膜上分层了p型和n型有机半导体，并研究了其光电化学行为如下。 1)发现亲水通道中物质传输的最佳温度相对高于室温。 2)温度依赖的光氧化速率进行了评估的p-n结。 此外，我们还提出了一种新的有机光催化剂单程流动反应器的概念，其中每一层的最佳吸收率进行了评估，第一次。
