here is due to its three arene groups arranged on the vertices around the trisubstituted benzene facet (Fig. ). Unlike in similar cycloimine cages where the helicity, or axial chirality, is an intrinsic property of the cage, 14 B11 does not inherently possess chirality. However, as with other triaryl-type molecules, it is able to form propeller-like conformations depending on the orientation of the arene groups on the vertices. DFT calculations performed on the single molecule show there is no unidirectional tilting of the aromatic rings on the vertices forming propeller-like chirality, but these propeller-like conformations could potentially be accessible through favourable supramolecular interactions, introducing chirality in the otherwise achiral cages. From examining the solid-state structure of B11 as explored by Greenaway et al., propeller like conformations form around the c-axis in the ab-plane of the crystal structure (Fig. ). As the propeller-like conformation is not seen in the single molecule (based on the reported DFT calculations), we sought to determine here whether the emergence of the propeller-like behaviour in the solid state is an artifact of the dynamic nature of the aryl groups, or whether the solid-state supramolecular interactions between the cages drive the chirality. Recently, we developed a new methodology to predict the packing of POCs based on local interactions between cages. This approach works by approximating the geometry of the POCs to hard polyhedral shapes and condensing the intermolecular interactions to be approximated as the key interactions that drive the packing between different POC facets.
