Abstract The cover picture shows the chemically induced reversible cycling of a BODIPY‐based dyad from the dark quinone state to the highly emissive hydroquinone form. The change in luminescence intensity can be readily seen by the eye. The phenylene spacer between the BODIPY and the redox‐active units is essential to the operation of the molecular dyads. Without this group, the fluorescence from the BODIPY group is quenched in both the quinone and hydroquinone forms. The reason for the difference in behaviour is discussed in the article by A. C. Benniston et al. on p. 2705 ff, along with the full details of the synthesis, structural, and sensing capabilities of the molecular systems.
