A bola-type π-conjugated amphiphile containing Phe-Lys dipeptide showed a pH- and guest-induced phase transition from the granular aggregate to the fibrous architecture and formed a supramolecular hydrogel. Using this stimuli-responsiveness, the hydrogel system was successfully applied to the selective discrimination of glycosaminoglycans composed of a sulfated sugar unit.
