以富瓦稀金属络合物为框架的太阳能储存分子

According to the caculation of the specialists of energy, with the most economical consumption of coal, oil, natural gas and etc., all the fossil will be exhausted after 100 years. Therefore, there will be an urgent need of finding a way to utilize the clean and sustainable solar energy. This project will be focused on harvesting solar energy and convert it to chemical bond energy and release it as heat when need. Compared to the traditional photovoltaics and solar thermal power which need a huge amount of mirrors, the fulvalene dimetal complexes based solar energy storage device which can be conveniently transported, can store energy for a long time and release the energy as heat on demand. Currently, the only successful system is the fulvalene diruthenium complex. As ruthenium is the expensive metal, the core research of this project will be based on the development of the highly efficient triplet sensitizer for the much cheaper and easier to get fulvalene diiron complex, ideally recyclable, for the pupose of storing and utilizing solar energy in the photoisomer as chemical bond energy.

根据能源专家的计算，即使以目前最经济的方式来消耗煤碳、石油、天然气等化石燃料，人类所能获得的能量供给也仅仅能够维持100年。由此，发展高效且便利的方法来利用清洁可持续的太阳能是当务之急。本课题将专注于吸收并转换太阳能于有机金属络合物的化学键中存储，并在需要时以热能的形式释放利用。相比传统需要大量光反射镜的太阳能光伏、太阳能热电，以富瓦稀二金属络合物为核心的太阳能吸收装置具有方便转移、可长久存储能量、能够按需释放能量等多种优点。目前成功的体系仅限于以富瓦稀二钌为核心的络合物，但钌是一种贵金属，因此本课题的核心研究将专注于设计合成出高效的三线态敏化剂，使得便宜易得的富瓦稀二铁络合物的光异构化成为可能，最终实现太阳能的存储与利用。
