Responsive supramoleculargels were constructed from crownether terminated four‐arm star poly(ε‐caprolactone) (PCL–DB24C8) and dibenzylammonium‐terminated two‐arm PCL–DBAS (see scheme), exploiting the formation of pseudorotaxane linkages between crownether and ammonium moieties. The resultant supramoleculargels exhibit thermo‐ and pH‐induced reversible gel–sol transition.
