    • However, these compounds were poorly characterized by present day standards, relying primarily on elemental analysis and molecular weight determinations for structural elucidation, with no further investigations into their resulting optical or electronic properties.

    • The NICS method is a measure of the abnormal proton chemical shift of aromatic molecules by the induced ring current that is due to cyclic σ or π electron delocalization, and whose values can either be negative (suggestive of diatropic ring currents and aromaticity) or positive (suggestive of paratropic ring currents and antiaromaticity). The standard method for NICS calculations is NICS(1), which is calculated at a distance of 1 Å above the plane of the ring in order to minimize the influence from the σ framework while maximizing the contributions from the π system.

    • 6 rings of 5 had NICS values similar to those of benzene (-10.33 ppm), indicating a high degree of aromaticity in these rings.
