摘要

在24到48的范围内构造了轴测投影和相应的富勒烯图。根据碳二聚体嵌入初始富勒烯六边形的机理,研究了富勒烯的生长。这导致了与产生张力平行的共价键的拉伸和断裂。在这种情况下,不是六边形与两个五边形相邻,而是两个相邻的五边形与两个六边形相邻。结果,产生了新的原子构型,两个碳原子的质量增加。我们考虑富勒烯C24的直系后代;即C2n,其中n = 13-24。

Geometric modeling of midi-fullerenes growth from C24 to C48

Axonometric projections together with corresponding graphs for fullerenes are constructed in the range from 24 to 48. The growth of fullerenes is studied on the basis of the mechanism, according to which a carbon dimer embeds in a hexagon of an initial fullerene. This leads to stretching and breaking the covalent bonds which are parallel to arising tensile forces. In this case, instead of the hexagon adjoining two pentagons, one obtains two adjacent pentagons adjoining two hexagons. As a result, there arises a new atomic configuration and there is mass increase of two carbon atoms. We considered direct descendants of fullerene C24; namely, C2n, where n = 13–24.
