| The unique molecular structures of carbon nanotubes grant them the potential to be revolutionary electronic and chemical materials. Further exploration of their properties requires a uniform sample of nanotubes with a specific diameter and ring-orientation. This work describes the progress made towards the chemical synthesis of a [6,6] arm-chair single walled carbon nanotube with 6-fold symmetry. The strategy undertaken involves the synthesis of a C60H12 hemispherical endcap, which will subsequently be elongated to the desired nanotube. The proposed pathway includes regioselective functionalization of the polycyclic aromatic hydrocarbon dibenzo[a,g]corannulene, dimerization of the C28H14 bowl, and precedented pyrolysis of an anhydride precursor to the target end cap. The curved building block, dibenzo[a,g]corannulene, has been successfully synthesized by two independent routes employing similar precursors: 1) flash vacuum pyrolysis and 2) double intramolecular arylation reactions.
