Multiple stimuli-responsive supramolecular gels constructed from metal–organic cycles

Abstract

Two supramolecular networks are constructed from a crown ether based metal–organic cycle and dibenzylammonium based poly(ε-caprolactone)s through multiple host–guest interactions. One of the networks can form organogels at higher concentrations, which show multiple stimuli-responsive behaviors under external stimuli, such as temperature, pH and ions.
