自从Krtschmer及其合作者于1990年宣布在实验室成功地常量制备并分离出稳定存在的C_(60)和C_(70)原子簇以来,人们对这类新型分子的研究寄予了极大的热情与期望,从不同角度对这类碳素多面体进行研究,已经获得的某些成果已见综述。就C_(60)分子的结构而言,Kroto等人提出,它是三十二面体的球形结构,由12个五边形和20个六边形相互连接构成,顶角数是60,60个碳原子分别置于各顶角位置。每个碳原子采用sp~2杂化,以三个单
Since Körtschmer and his collaborators announced in 1990 that they successfully and consistently prepared and isolated C_ (60) and C_ (70) clusters in the laboratory, there has been a great deal of enthusiasm for the study of these new molecules And expectations, from a different perspective on the carbon polyhedron research, some of the results have been obtained have been reviewed. In terms of the structure of the C60 molecule, Kroto et al. Propose that it is a dodecahedron spheroidal structure consisting of 12 pentagons and 20 hexagons connected to each other with a vertex angle of 60, 60 Carbon atoms were placed in the top corner position. Each carbon atom using sp ~ 2 hybrid to three single
