A supramolecular gelator based on the bistable [c2]daisy chain rotaxane is designed and synthesized.The reversible actuation of the [c2]daisy chain renders the formed supramolecular gel with acid/base-responsive switching between gel and monomer solution.The efficient switching process is attributed to the ring-sliding effect of the rotaxane in response to acid/base stimuli.The ring-inhibited hydrogen bonding stacking results in a nearly quantitatively disassembly of the gel network after addition of base which is hard to be realized by traditional heating strategy in hydrogen-bonding-supported gel.
