It should be stressed that the study is aimed at establishing the type of aromaticity, not the quantitative extent of aromaticity. We utilize primarily the B3LYP functional with the 6-311G(d,p) basis set. This functional is known to exaggerate aromaticity in macrocycles when compared to long-range corrected functionals (e.g., CAM-B3LYP), which are recommended for such molecules and for aromatic compounds in general. Calculations with CAM-B3LYP are, however, performed on selected species (see Tables and in the SI).
