A transient non-covalent hydrogel by a supramolecular gelator with dynamic covalent bonds
New Journal of Chemistry, 2021In aqueous solution, equilibrium self-assembly and gelation occur at higher concentration but on addition of EDC non-equilibrium self-assembly and transient hydrogels are formed at low concentration, which dissolve upon anhydride hydrolysis.

Hydrogen‐Bond Catalysis of Imine Exchange in Dynamic Covalent Systems
Chemistry – A European Journal, 2020AbstractThe reversibility of imine bonds has been exploited to great effect in the field of dynamic covalent chemistry, with applications such as preparation of functional systems, dynamic materials, molecular machines, and covalent organic frameworks. However, acid catalysis is commonly needed for efficient equilibration of imine mixtures.

Readily Recyclable Thermosets Based on Dynamic Covalent Bonds
2020Thermosetting polymers have played an important and irreplaceable role, such as adhesives, coatings, composites, etc., while they are difficult to be recycled due to their permanent crosslinked networks. The last few years have witnessed the rapid development of thermosetting polymers based on dynamic covalent bonds, also known as covalent adaptable ...

H-Shaped Supra-Amphiphiles Based on a Dynamic Covalent Bond
Langmuir, 2012The imine bond, a kind of dynamic covalent bond, is used to bind two bolaform amphiphiles together with spacers, yielding H-shaped supra-amphiphiles. Micellar aggregates formed by the self-assembly of the H-shaped supra-amphiphiles are observed. When pH is tuned down from basic to slightly acidic, the benzoic imine bond can be hydrolyzed, leading to ...

Shape‐Persistent Organic Cage Compounds by Dynamic Covalent Bond Formation
Angewandte Chemie International Edition, 2010AbstractOne area of supramolecular chemistry involves the synthesis of discrete three‐dimensional molecules or supramolecular aggregates through the coordination of metals. This field also concerns the chemistry of supramolecular cage compounds constructed through the use of such coordination bonds.

Self-assembled poly[2]catenanes based on non-covalent and dynamic covalent bonds
Polymer ChemistryWe report totally self-assembled poly[2]catenanes from M1 and M2 based on non-covalent and dynamic covalent bonds. M1 first self-assembled into SPs. Then, the addition of M2 induced dynamic covalent assembly with SPs to form poly[2]catenanes.
