has been found to be very effective in solubilizing single-walled
carbon nanotubes in tetrahydrofuran. Solubilizing efficiency is close
to the commonly used anionic surfactant, sodium dodecyl sulfate (SDS).
Corannulene derivative has also been found to have a tendency to disperse
metallic nanotubes more effectively than the SDS counterpart. Theoretical
calculations predict higher dispersion interactions of corannulene
backbone with the convex surface of nanotubes in comparison to those
calculated with other commonly used polyaromatic hydrocarbon derivatives.
