Abstract
2D/2D fusion of aromatic halves leading to a global aromatic is found in many polycyclic aromatic hydrocarbons. 3D/3D aromaticity is also found in fused boranes that follow the Jemmis’ mno rule, but 2D/3D aromaticity is difficult or impossible to achieve.

Description
Table S1. NICS (in ppm) and MCI (in e) of rings of fused carborane and PAH system, and relative
energies compared to the most stable isomer.
Table S2. NICS and MCI of C2B10H12 and reference PAHs.
Fig. S1. Bond lengths of the PAHs.
Table S3. Cartesian coordinates of 3D/3D fused systems.
Table S4. Cartesian coordinates of fused systems between carborane and PAHs.
Table S5. Cartesian coordinates of reference aromatic systems.
Table S6. Bond length alternation for the series of compounds under analysis. BLA has been
computed as the longest and shortest bond lengths for each system. In the fused systems, no atom
involved in the fusion between the two units has been considered. Only B-B bonds have been
considered for the carboranes.
