Good form : Attaching a flexible piperidine unit to 4‐(phenyldiazenyl)naphthalen‐1‐ol allows construction of a tautomeric switch, where directed shift of the tautomeric equilibrium can be achieved through protonation and deprotonation (see picture). The developed molecular switch shows acceptable complexation with small alkali‐ and alkaline‐earth‐metal ions and forms a promising base for further development of effective molecular sensors.
