Self-Healing Supramolecular Gels Formed by Crown Ether Based Host-Guest Interactions

Automatic repair: A polymer with pendent dibenzo[24]crown‐8 units (purple in picture) was cross‐linked by two bisammonium salts (green) to form two supramolecular gels based on host–guest interactions. These two gels are stimuli‐responsive materials that respond to changes of the pH value and are al...

Description
Summary:Automatic repair: A polymer with pendent dibenzo[24]crown‐8 units (purple in picture) was cross‐linked by two bisammonium salts (green) to form two supramolecular gels based on host–guest interactions. These two gels are stimuli‐responsive materials that respond to changes of the pH value and are also self‐healing materials, as can be seen by eye and as evidenced by rheological data.
