Abstract

Stimuli-responsive gels that can change their volumes drastically in response to various external physical and chemical stimuli have been of much interest due to their various applications. Herein, novel stimuli-responsive gels were achieved through the complexation between anion receptors and the chloride anion of polystyrene ionomer gels in aprotic organic solvents. The volume expansions induced by the addition of the receptors originated from breaking the aggregation of ionic groups and enhancing the dissociation of the ion-pairs, accompanied by their colour changes.
