“…Supramolecular elastomers combine the properties of both elastomers and noncovalent interactions. Owing to the reversible dynamics of noncovalent interactions, supramolecular elastomers can respond to external stimuli, leading to smart behaviors such as self-healing, − shape memory, − reversible adhesion, − and photothermal- or humidity-responsive functions. − Notably, metallosupramolecular elastomers based on metal–ligand coordination interactions possess a broad range of material properties through the choice of different ligands, metal ions, and counterions. − In particular, detailed studies in solutions have revealed that the choice of ligands and metal salts significantly affects the kinetic and thermodynamic binding properties of coordination complexes. ,− However, in metallosupramolecular elastomers, the metal–ligand coordination chemistry is applied in the solid state, , and the binding constants of metal–ligand complexes measured in solutions cannot give accurate theoretical guidance, and meanwhile, the supramolecular interactions in solutions may be counteracted by secondary effects in the solid state . Therefore, the factors influencing the properties of metallosupramolecular elastomers have their unique complexity.…”
