On the alleged bicycloaromaticity of 2 and 3. We start with the two dithiophenobridged octaphyrins 2 and 3 as they link PAHs with the cage-type macrocycles. Macrocycles 2 and 3 were recently labelled as bicycloaromatic, a form of aromaticity defined by Goldstein as a case where three separate -conjugated polyene segments (ribbons) in a bicyclic CmHm hydrocarbon interact through-space in either a longicyclic or a laticyclic topology (Figure ). Two criteria must be fulfilled for a bicycloaromatic interaction; (i) m must be an odd number (i.e., odd number of C and H atoms), and (ii) the total number of π-electrons must equal 4n.
