Dynamic covalent polymers
This Highlight presents an overview of the rapidly growing field of dynamic covalent polymers. This class of polymers combines intrinsic reversibility with the robustness of covalent bonds, thus enabling formation of mechanically stable, polymer-based materials that are responsive to external stimuli. It will be discussed how the inherent dynamic nature of the dynamic covalent bonds on the mole...
متن کاملSynthesis and solid state structure of a hydrazone-disulfide macrocycle and its dynamic covalent ring-opening under acidic and basic conditions.
The synthesis and characterisation, including solid state structure, of a macrocycle containing both a hydrazone and a disulfide linkage is described. Selective ring-opening of the macrocycle under thermodynamic control could be achieved at either the disulfide or the hydrazone linkage by applying mutually exclusive sets of reaction conditions.
متن کاملPhosphine-mediated disulfide metathesis in aqueous media.
Dynamic carbohydrate systems have been efficiently generated through phosphine-mediated disulfide metathesis in aqueous media. The protein compatibility and binding features of the dynamic systems were demonstrated in situ using (1)H STD NMR.
متن کاملReorganization of polymer structures based on dynamic covalent chemistry: polymer reactions by dynamic covalent exchanges of alkoxyamine units
The recent progress of research on polymer reactions utilizing dynamic covalent exchanges of alkoxyamine units—adducts of styryl and stable nitroxide radicals—is reviewed. The alkoxyamine derivatives derived from 2,2,6,6-tetramethylpiperidine-1-oxy (TEMPO, a stable free radical) are frequently utilized as unimolecular initiators for the nitroxide-mediated radical polymerizations. In the absence...
متن کاملDynamic combinatorial libraries of disulfide cages in water.
[structure: see text] Dynamic combinatorial libraries (DCLs) containing water-soluble disulfide-linked cages (alongside macrocyclic structures) have been generated and characterized. Unlike most other strategies for generating molecular cages, the structures are held together by covalent bonds, which are formed under thermodynamic control. The diversity of the cages generated opens new possibil...
