Responsive supramolecular gels were constructed from crown ether terminated four-arm star poly(e-caprolactone) (PCL-DB24C8) and dibenzylammonium- terminated two-arm PCL-DBAS (see scheme), exploiting the formation of pseudorotaxane linkages between crown ether and ammonium moieties. The resultant supramolecular gels exhibit thermo- and pH-induced reversible gel-sol transition.
