| 摘 要： | 随着“足球烃”C_(60)及其他“球碳烃”的发现,以及对它们奇妙的结构与化学行为的不断揭示,碳原子簇的产生与研究已成为当前化学界的一个热门课题.Smalley等最近又将C_(60)中的一个碳原子以硼原子取代,成为Lewis酸,使这方面的研究更加深入。近二年来,我们在自制的装置上对碳原子簇的结构作了较为充分的研究后,又以独特的方式产生了链状构型的C_nB~-,记录了它们的负离子质谱。

| Abstract: | Time-of-flight mass spectrum of C_nB~- has been recorded on a selfbuilt instru-ment with laser vaporization of tetraphenylboron sodium. By analysis of the com-position of the anions, it is found that number of the boron atoms in any of theseions equals to the number of the charges carried by the anion, and the sum of thenumbers of the carbon and boron atoms in these species are always the odd numbers.The experimental results show that boron atom has a strong tendency to attract anelectron so that those C_nB~- will have similar electronic structures as C_n, and carbonclusters with odd members are always more stable than their even neighbors. |
