Engineering molecular chains in carbon nanotubes
Chamberlain, Thomas W.; Pfeiffer, Rudolf; Howells, Jonathan; Peterlik, H.; Kuzmany, H.; Kräutler, B.; Da Ros, T.; Melle-Franco, M.; Zerbetto, F.A range of mono- and bis-functionalised fullerenes have been synthesised and inserted into single-walled carbon nanotubes. The effect of the size and shape of the functional groups of the fullerenes on the resultant 1D arrays formed within the nanotubes was investigated by high resolution transmission electron microscopy and X-ray diffraction. The addition of non-planar, sterically bulky chains to the fullerene...
Graphene nanoribbons from carbon nanotubes
Cunha, Eunice Paula Freitas; Paiva, M. C.; Proença, M. Fernanda R. P.; Melle-Franco, M.; Costa, Florinda; Fernandes, António J.; Torres, VítorChemical functionalization of the outer graphene layer of carbon nanotubes (CNT) has been increasingly studied, aiming at the application of CNT in different areas. The functionalization of CNT using the 1,3-dipolar cycloaddition reaction, leading to the formation of cyclic amine groups on the CNT surface [1], was observed to induce the unzipping of the CNT under specific conditions. The CNTs thus functionalize...
