The square can play the pentagon's game of inducing curvature into aromatic molecules. In their Communication on page 399 ff., B. T. King and co‐workers report the synthesis of a [4]circulene, a compound with four fused benzenoid rings that form an internal square. Contrary to expectations, this deep‐bowl‐shaped quadrannulene is stable, thereby reflecting its radialene nature.
