Studies on the Synthesis, Separation and Characterization of Isolated-Pentagon-Ring-Incorporating Fullerenes and Related Derivative from Flame

Abstract

自从1985年Kroto等在实验室证实富勒烯C60以来,这个碳的第三种同素异形体引起了世界各国科学家们的兴趣和关注,同时被誉为继1825年苯被发现以来的最大发现,从此富勒烯相关领域的研究得到了迅速发展。目前,人们一直致力于对富勒烯新物种的发现和表征、富勒烯的物理和化学性质以及富勒烯在各个领域应用的研究。对于具有独立五元环的富勒烯如C60,C70等已经能够大量合成出来;而对于具有相邻五元环的富勒烯及其衍生物,由于其结构本身具有较大的张力导致其化学性质很活泼而不稳定,它们的合成、分离和表征具有很大的挑战性,目前主要是通过石墨电弧放电法以内嵌或外接的方式将它们稳定下来并分离得到。但由于合成的量太少制...Since fullerene (e.g. C60), the third allotrope of carbon, was confirmed by Kroto et al. in 1985, it has attracted interests and attentions of scientists from all over the world. It was regarded as another most important achievement after the discovery of benzene in 1825, and the research on fullerene was developed prosperously. Nowadays, most of research activity are focused on three fields: 1) f...学位:理学博士院系专业:化学化工学院化学系_无机化学学号:2052007015358
