    富勒烯家族有着数量庞大的碳笼异构体,其中最常见的是符合独立五元环 (IPR)规则的Ih-#1,812C60和D5h-#8,149C70。根据IPR规则,富勒烯碳笼上的所有五 元环均被六元环分隔开的结构(IPR富勒烯)才是稳定的,而那些含有相邻五元 环的碳笼(非IPR富勒烯)则是活泼的、不稳定的。实际上,对于碳数小于70的 碳笼,除了Ih-C60,其他的碳笼均不可避免的含有相邻五元环。对某一碳数的富 勒烯,非IPR富勒烯异构体的数量远远大于IPR富勒烯。目前,得到表征的非IPR富 勒烯已有数十种,然而关于非IPR富勒烯的稳定性和反应性的理论研究,还需要 更多的实验结果来佐证和补充。...There are a huge number of isomers in fullerene family. The most common fullerenes are Ih-#1,812C60 and D5h-#8,149C70 which obey the isolated pentagon rule (IPR).According to the isolated pentagon rule, which states that the fullerenes with isolated pentagon rings separated by hexagon rings are stable. These kind of stable fullerenes with isolated pentagon rings are called IPR fullerenes. Otherwi...学位:理学博士院系专业:化学化工学院_无机化学学号:2052010015365

    会议地点:中国天津[英文文摘]Chlorofullerenes are valuable reactants for further derivation. The fullerenes chlorides synthesized so far are considerably less than those of bromides and fluorides. To date, only C60Cl6 can be macroscopically synthesized. Here we report a facile synthesis of Ih-C60Cl8 and Ih-C60Cl10, as well as their separation and analyses

Xiamen Univ, Coll Chem & Chem Engn, Dept Chem, Xiamen 361005, Peoples R ChinaA long-sought empty non-IPR fullerene, C-#11188(72), which is more stable than the sole IPR isomer in the fullerene[72] family, has been retrieved and crystallographically characterized as (C72Cl4)-C-#11188. Mass spectrometric data support the facile dechlorination of (C72Cl4)-C-#11188 and, in turn, the possible stability of pristine C-#11188(72).NNSF of China 21031004,20721001 ,20525103 973 Program 2007CB815301,2011CB935901 NFFTBS J103041
