Design of true -conjugated 3D-aromatics. Having refuted the claims of the bicycloaromaticity of 2 and 3 as well as the 3D-aromaticity of 1 and 1 6+ , how to design conjugated (macrocyclic) cage molecules that are truly 3D-aromatic? As it is the higher-order point groups that exhibit irreducible representations with triple (or higher) degeneracies, leading to species that possibly can be 3D-aromatic, a -conjugated macrocycle which is 3D-aromatic must have (approximate) tetrahedral, octahedral or icosahedral, or even higher symmetry.
