Metallo-supramolecular micellar hydrogels exhibiting thermo-mechanical responsiveness have been prepared through the hierarchical assembly of a heterotelechelic associating copolymer. The latter consists in a linear thermo-sensitive water-soluble sequence terminated by a short hydrophobic sticker at one end, the other being functionalized by a chelating ligand. As a first level of assembly, the associating copolymer is dissolved in water to yield micellar nanostructures, bearing ligands at the end of the coronal chains. The second level of assembly is achieved when transition metal ions are added to the micellar solutions, resulting in almost instantaneous gelation. The thermo-mechanical response of those materials is investigated in detail.
