Construction of polyrotaxanes via reversible chain exchange between acylhydrazone bonds.
نویسندگان
چکیده
By simply heating mixtures of alpha-cyclodextrins and dumbbell-like poly(ethylene glycol) derivatives at 120 degrees C, polyrotaxanes form spontaneously via reversible chain exchange between acylhydrazone bonds, which have been proven by analyses of diffusion-ordered NMR, WAXD, 1H NMR, solid-state 13C CP/MAS NMR, DSC and UV-Vis together.

متن کاملSingle-Chain Polymer Nanoparticles via Non-Covalent and Dynamic Covalent Bonds
The added-value behind reversible bonds is the possibility to develop responsive structurally dynamic materials which can adapt their constitution and, hence, properties to external stimuli. In recent years, much effort has been devoted to the design and synthesis of single-chain polymer nanoparticles (SCNPs) that can be reversibly assembled / disassembled in response to external environmental ...
متن کاملSupramolecular hydrogels formed from poly(viologen) cross-linked with cyclodextrin dimers and their physical properties
Supramolecular materials with noncovalent bonds have attracted much attention due to their exclusive properties differentiating them from materials formed solely by covalent bonds. Especially interesting are rotor molecules of topological complexes that shuttle along a polymer chain. The shuttling of these molecules should greatly improve the tension strength. Our research employs cyclodextrin ...
متن کاملTemplating a polymer-scaffolded dynamic combinatorial libraryw
Dynamic combinatorial chemistry (DCC) has emerged in recent years as a powerful tool for the discovery of molecular receptors. DCC uses reversible covalent reactions to link together building blocks, forming libraries of compounds whose product distributions are under thermodynamic control. The reversible nature of the linkages enables the library members to reconfigure their structures by exch...
