Metal‐ligand coordination and host–guest recognition are introduced into the hybrid system in order to prepare supramolecular gels, which can be responsive to multiple external stimuli such as metal ions, competitive guest/host molecules, and oxidants. To this end, the triangular terpyridine‐based metallocycles functionalized with 1‐adamantyl and ferrocenyl groups are constructed through self‐assembly, and further used as supramolecular cross‐linkers for gelation of β‐CD‐containing copolymers. Their gelation and stimuli‐response tests are discussed, and an application of the metallotriangles for serving as supramolecular glue is demonstrated through a series of adhesion experiments. This approach enables facile access to construction of multifunctional metallosupramolecules as well as functional hybrid materials.
