Given the correlation between low energy structures in the CSP landscapes and their experimental counterparts, we analysed the packing motifs in the lowest energy polymorphs for both enantiopure and racemic structures for naphthalene and [3]- [12]helicene to look for similarities between the packing behaviour of the polymorphs with different number of aromatic rings (Fig. ). For the enantiopure structures, [4]helicene exhibits both herringbone-type packing and translational chains of helicenes that are similar to the adjacent translational chains as established in Ref. 26, whereas [5]helicene does not exhibit any packing motifs seen in the CSP landscape of [6]helicene. The [6], [7], and [8]helicenes are dominated by chains of interlocked pairs, whereas for n > 8, this packing behaviour changes and there is less interlocking between neighbouring helicenes.
