英文摘要： [60]Fullerene is excellent electron and energy receptor, which can speed up charge separation and extend the lifetime of the charge separated state. This project aims to synthesize a series of Ru(II)/Os(II)/[60]fullerene polypyridyl complexes by introducing [60]fullerene into Ru(II)/Os(II) polypyridyl complexes via alkynyl or aromatic conjugate group. Studying the properties of electron or energy transfer and lifetime of the charge separated state of the complexes. Discussing the impacts of different situation, such as the number and location of fullerene and metal centers on the properties of the complexes. On this basis, understanding the regulatory mechanisms of excited state properties of the complexes by fullerene and summing up the relationship between the properties and structure to screen out the complexes with excellent electron or energy transfer and long-lived charge separated state properties. Solving the bottleneck which obstructs the research and application of the Ru(II)/Os(II) polypyridyl complexes, at the same time, providing the experimental and theoretical basis for the development of novel transition metal complexes with easy synthesizing, low cost, excellent optical and electrical properties.
