The analyses and discussions of our findings are split in three sections; a first with the qualitative theory on bicycloaromaticity, 3D-aromaticity, and 2D-aromaticity in threedimensional compounds (briefly, 2D-aromaticity-in-3D), a second with computational results of these compounds discussed within the theoretical framework described in the first section, and a third where we explore species that can be truly -conjugated 3D-aromatics.
