摘要
Density functional computations show, in contrast to general assumptions, that the reactions at the 7-7 ring fusions of Stone-Wales defects in the sidewalls of armchair (5,5) single-wall carbon nanotubes are much less exothermic than reactions at perfect sites. In addition, the peripheral 5-6 and 6-7 ring fusions of the defect are much more reactive. Copyright © 2005 American Chemical Society.
