Modular synthetic strategy constructs non-benzenoid polycyclic aromatic hydrocarbons, indicating intriguing properties.
A modular synthetic strategy based on sterically controlled 5- exo -dig cyclization enables the construction of stable non-benzenoid PAHs featuring indacene, pentalene, and azulene motifs, exhibiting tunable (anti)aromaticity and diradical character.
