The hydrogels based on the co-assembly of bolaamphiphilic L-histidine and 2,2'-bipyridine-dicarboxylic acids were transformed into viscoelastic supramolecular polymers by cross-linking with Cu(II) ions, and macroscopic supramolecular yarns were obtained by direct drawing from a dilute aqueous solution of the supramolecular polymers.
