Abstract
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.
