  • Patent number: 10865290
    Abstract: A supramolecular polymer with living characteristics is provided based on small molecules or metal complexes of a planar or linear geometry and a polymer. The small molecules are solvophobic and can associate or assemble with each other through non-covalent interactions such as but not limited to metal-metal, ?-?, hydrogen-bonding, and/or solvophobic-solvophobic interactions, in the modulation of the polymer. The polymer has affinity to the medium (e.g., solvent) and still interacts with the small molecules via non-covalent interactions such as electrostatic attractions to stabilize the associated/assembled small molecules. Varying the composition and/or length of the polymer can modulate the dimensions of the supramolecular polymer and the nanostructures therefrom. The two- or multi-component supramolecular polymer has active ends to support further supramolecular polymerization upon addition of small molecules of a planar or linear geometry.
