英文摘要： Fullerenes and their derivatives are one kinds of novel acceptor materials in bulk heterojunction polymer solar cells due to their unique electronic and optical properties. This project is aimed to design and synthesize some novel bisadduct [60]fullerene derivatives containing substituted indene, substituted dihydronaphthene, porphyrin, tetrathiafulvalene and ferrocene groups, to explore a condition to control the selectivity and the yield for [60]fullerene derivatization, to obtain bisadducts of [60]fullerene with special composition and structures, to study their photophysical and electrochemical properties and investigate the relationship between materials structure and properties, in order to obtain novel bisadduct [60]fullerene derivatives with good solubility, high electron mobility and high LUMO energy levels. These bisadduct [60]fullerene derivatives will be used as acceptors in polymer solar cells while poly(3-hexylthiophene) (P3HT) as donor, their photovoltaic performance will be tested and optimized to explore the mechanism for the generation of photocurrent and electron transfer and to provide a theoretical basement and pay a way to design practical polymer solar cells. Therefore this project has not only academic meanings but also promising practical values, and will support the development of fulle
