Steps toward the synthesis of a geodesic C60H12 end cap for a C3v carbon [6,6]nanotube

Several shape-persistent carbon-rich nanomolecules with diameters exceeding 1.7 nm have been prepared by the aldol trimerization of 20-carbon aromatic ketones bearing chlorine atoms at Various sites. These C60H27Cl3 and C60H24Cl6 polycyclic aromatic compounds represent attractive intermediates for the synthesis of a geodesic C60H12 end cap of a C-3v carbon [6,6]nanotube. (C) 2008 Elsevier Ltd.
