چکیده

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.

A supramolecular triarm star polymer from a homotritopic tris(crown ether) host and a complementary monotopic paraquat-terminated polystyrene guest by a supramolecular coupling method.

The first supramolecular star polymer based on pseudorotaxane host-guest complexation was prepared from statistical complexation of a homotritopic tris(crown ether) host and monotopic paraquat-terminated polystyrene guest in solution. The formation of this supramolecular star polymer was confirmed by proton NMR characterization and viscosity studies.

Redox-responsive self-healing materials formed from host–guest polymers

Expanding the useful lifespan of materials is becoming highly desirable, and self-healing and self-repairing materials may become valuable commodities. The formation of supramolecular materials through host-guest interactions is a powerful method to create non-conventional materials. Here we report the formation of supramolecular hydrogels and their redox-responsive and self-healing properties ...

Responsive supramolecular gels constructed by crown ether based molecular recognition.

Responsive supramolecular gels were constructed from crown ether terminated four-arm star poly(epsilon-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.

Aqueous interfacial gels assembled from small molecule supramolecular polymers

The self-assembly of a stimuli-responsive aqueous supramolecular hyperbranched polymer from small molecules is reported. This system is composed of ditopic and tritopic guest-functionalised molecules that are able to form heteroternary supramolecular complexes with the macrocyclic host cucurbit[8]uril (CB[8]). We demonstrate that the supramolecular hyperbranched polymer formed is responsive to ...
