A missing link has been discovered. In their Communication on p. 1072 ff., F. Teplý et al. describe the three‐step synthesis of helquats, a novel class of small helical dications representing a missing structural link between helicenes and viologens. Bridging these areas, until now separate, is anticipated to open up unknown scientific territories. The parent helquat is a water‐soluble, blue fluorophore and can be prepared by a unique metal‐catalyzed [2+2+2] cycloisomerization in water under aerobic conditions.
