Enhanced pi-pi interactions between a C-60 fullerene and a buckle bend on a double-walled carbon nanotube
NANO RESEARCH, 3:92-97, FEB 2010
In situ low-voltage aberration corrected transmission electron microscopy (TEM) observations of the dynamic entrapment of a C-60 molecule in the saddle of a bent double-walled carbon nanotube is presented. The fullerene interaction is non-covalent, suggesting that enhanced pi-pi interactions (van der Waals forces) are responsible. Classical molecular dynamics calculations confirm that the increased interaction area associated with a buckle is sufficient to trap a fullerene. Moreover, they show hopping behavior in agreement with our experimental observations. Our findings further our understanding of carbon nanostructure interactions, which are important in the rapidly developing field of low-voltage aberration corrected TEM and nano-carbon device fabrication.
