Switchable supramolecular polymers from the self-assembly of a small monomer with two orthogonal binding interactions

10.1021/ja200941a

The study investigates the reversible formation of linear main-chain supramolecular polymers using a small ditopic monomer 1 that features two orthogonal binding interactions: metal-ligand binding and ion pair formation. The monomer 1 consists of a terpyridine ligand attached to a self-complementary guanidiniocarbonyl pyrrole carboxylate zwitterion. The terpyridine ligand forms a 1:2 metal complex with Fe(II) ions, while the zwitterion dimerizes through ion pairs. These interactions drive the self-assembly of monomer 1 into linear supramolecular polymers in polar solvents like DMSO and water. The polymerization can be reversibly controlled by adding or removing metal ions (using a competing ligand like HEEDTA) or by adjusting the pH to protonate or deprotonate the zwitterion. The study employs various techniques, including UV/vis spectroscopy, viscosity measurements, TEM, cryo-TEM, DLS, and SANS, to demonstrate the formation of linear polymers that further aggregate into larger globular structures. The findings highlight the potential of this system for developing stimuli-responsive materials.
