Shielding Cone in Spherical Aromatic Structures. Insights from Models for Spherical 2(N+1)2 Aromatic Fullerenes
A direct correlation between - and spherical aromaticity is established by showing that they share a characteristic shielding cone, resulting from a specific orientation of the applied field. Here we unravel the presence of a related long-range shielding cone in spherical aromatic species accounted through C20, C32, C50 and C60 Hirsh aromatic fullerenes. It is found that meanwhile for planar aromatics, the cone is reserved only for a perpendicularly applied field, for spherical aromatic compounds, the tridimensional cage allows the formation of the shielding cone according to the given orientation of the external field.
