Abstract Gels generally comprise different intermolecular noncovalent interactions for sustaining self‐assembled structures, which renders them sensitive to external stimuli, while simultaneously sacrificing their stimuli‐responsive selectivity. Supramolecular and polymeric gels are constructed here by the coassembly of a dipyridinil phenol as crosslinker with gelator counterparts. In these systems, an ordered multiple H‐bonded network facilitates proton transferred tautomerization caused...
