人工光化学转换和光电转换，是有效利用太阳能、缓解能源危机和解决环境污染的重要手段。基于富勒烯C60的n-型有机半导体和窄带隙p-型有机半导体在人工光电转换领域取得了广泛应用，但有关两者在人工光化学转换中的研究十分匮乏，是该领域前沿。本项目针对人工光化学转换，设计合成一系列结构新颖的水溶性C60衍生物和具有推-拉电子结构的窄带隙p-型有机半导体；研究两者水溶液中的超分子自组装，构建高效、环保的人工光化学转换体系；探索光致电荷转移和能量传递及两者之间的互馈机制；揭示人工光化学转换体系的性能与半导体结构、超分子复合物形态三者之间的内在联系。. 项目的开展，能够拓宽可用于人工光化学转换的材料种类，深入推动人工光化学转换的研究。同时，有利于促进人工光化学转换与光电转换之间的交叉融合，为深入理解聚合物电池中激子的产生和扩散提供一个新视角，并为革新电池材料、开发环保型电池制备工艺提供借鉴。

Artificial photochemical conversion and photovoltaic conversion is currently an important means to effectively utilize solar energy and solve the engergy crisis and environmental pollution. Fullerene C60-based n-type and narrow bandgap p-type organic semiconductors have found tremendous applications in photovoltaics. However, only quite limited attention is paid to their applications in artificial photochemical conversion. In this project, a series of water-soluble C60 derivatives and narrow bandgap p-type organic semiconductors with push-pull structure motif will be designed, which are then used to construct highly effective and environmentally benign model systems toward artificial photochemical conversion in water through supramolecular self-assembly. Then, photoinduced electron and energy transfer within these structures and corresponding mechanisms will be investigated, taking into account the influences of the structures of C60 derivatives, p-type organic semiconductors and the supramolecular self-assemblies. . The implementation of this project will widen the types of materials which can be used for artifical photochemical conversion and push forward the investigation of artificial photochemical conversion. In addition, it could promote the chiastopic fusion between artificial photovoltaic and photochemical conversions and provide a new perspective to deep understand the formation and diffusion of excitons involved in polymer solar cells. It also acts as a benefecial reference toward developping environmentally-benign materials and strategies for solar cells.
