Dancing people parade along the rings: The cover image depicts the movement of electrons on tetracyclic π-conjugated systems under a magnetic field. While the annulation of benzene rings with a pentalene moiety resulted in the local aromatic character in the six-membered rings, the thiophene-fused analog retains the pronounced antiaromatic character of pentalene moiety. The fused thiophene rings also offer sufficient stability to the antiaromatic pentalene even without bulky substituents, enabling the formation of aggregates.
