Control of carbon nanotube handedness using a supramolecular chiral surface.
Sorting diameter and handedness of carbon nanotubes still appears as an important challenge in nanotechnology. In this context, supramolecular structures formed by self-assembled chiral molecules deposited on well-defined metal surfaces can be used to discriminate the two isomers of carbon nanotubes. Calculations are carried out to determine the adsorption energy of nanotube enantiomers on alaninate coated Cu(110) surface. The results show a significant discrimination of the L and R handed isomers by such a surface and an additional selectivity in terms of small and large tube diameters.
