基于核黄素的卟啉类长寿命电荷分离态组装体研究

合成具有长电荷分离态的卟啉组装体是实现模拟光合作用、提高太阳能光电转换效率的关键，但是目前基于C60等物种的组装体的电荷分离态寿命都不够长。本项目基于电荷传递重组能非常小的核黄素，运用分子设计与晶体工程技术，将核黄素与卟啉结合以获得长电荷分离态的卟啉-核黄素类组装体，并揭示其构筑规律；通过对卟啉-核黄素类组装体的电荷分离态寿命研究，探索组成和结构变化对电荷分离态寿命的影响，阐明组成和结构与电荷分离态寿命之间关系，从理论上证明和预测卟啉-核黄素类组装体的电荷分离态寿命调控机制；研究组装体的物理化学性能，为实际应用奠定基础，为设计和制备卟啉光电功能材料提供新方法和理论依据。本项目有助于丰富和发展卟啉功能材料相关理论和获得新型卟啉光电功能材料，有助于人们更好地对卟啉光电功能材料开展基础理论研究和实际应用研究，有助于在一定程度上改变人们在数量庞大的材料中一个个逐一发现新卟啉光电功能材料的研究模式。

The preparation of porphyrinic materials with a long-lived charge-separated state is the key to mimic natural photosynthesis process and to increase the efficiency of solar photoelectric conversion. However, up to date the lifetime of charge-separated state of porphyrinic assemblies based on C60 or other species is not long enough yet. The reorganization energy of riboflavin is very small and the lifetime of charge-separated state of a porphyrin-riboflavin assembly is possibly long. We will aim at the materials based on porphyrin-riboflavin assemblies. We are going to prepare novel porphyrin-riboflavin assemblies and reveal their construction rules and the relationships between their structures and properties by using molecular design and crystal engineering methods. This research will redound to enrich the theory of porphyrinic photoelectric functional materials, make for people to obtain novel porphyrinic photoelectric functional materials, help people to better promote the theoretical and practical investigations on porphyrinic photoelectric functional materials, and help people to innovate their research mode for one by one finding novel porphyrinic photoelectric functional materials from numerous compounds.
