A disulfide-bridged bispillar[5]arene was synthesized via efficient oxidation of thiol-pillar[5]arene. The resulting disulfide-bridged bispillar[5]arene was successfully applied in constructing linear supramolecular polymers which were confirmed by concentration-dependent 1H NMR spectroscopy, 2D DOSY and viscosity measurements. Such supramolecular polymers manifested redox responsiveness and were fabricated into water dispersible nanospheres with high fluorescence properties.
