Working principle of host-guest gel. (a) Preparation and chemical structure of βCD–Ad gel (x,x). x represents the mol% contents of βCD and Ad units. (b) Reversible switching of βCD–Ad bonds in response to free βCD molecules (purple) in solution. Under equilibrium, the fraction of βCD–Ad bonds connected to the polymer chains depends on βCD concentration, which allows for the dynamic modulation of Young’s modulus E.
