Single-Chain Polymer Nanoparticles via Non-Covalent and Dynamic Covalent Bonds

Single-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 ...

pH-responsive single-chain polymer nanoparticles utilising dynamic covalent enamine bonds.

Structurally dynamic single-chain polymer nanoparticles that can reversibly undergo a coil to particle transition via formation and cleavage of intramolecular dynamic enamine cross-links are reported.

Covalent Bonds

Functional systems with orthogonal dynamic covalent bonds.

This review summarizes the use of orthogonal dynamic covalent bonds to build functional systems. Dynamic covalent bonds are unique because of their dual nature. They can be as labile as non-covalent interactions or as permanent as covalent bonds, depending on conditions. Examples from nature, reaching from the role of disulfides in protein folding to thioester exchange in polyketide biosynthesi...

Constructing covalent organic frameworks in water via dynamic covalent bonding

The formation of keto-enamine based crystalline, porous polymers in water is investigated for the first time. Facile access to the Schiff base reaction in water has been exploited to synthesize stable porous structures using the principles of Dynamic Covalent Chemistry (DCC). Most credibly, the water-based Covalent Organic Frameworks (COFs) possess chemical as well as physical properties such a...
