Interplay between chalcogen bonds and dynamic covalent bonds

Organic Chemistry Frontiers, 2022
A combination of chalcogen bonds, one type of emerging non-covalent bonding force, and imine bonds, allow the control of the dynamic covalent chemistry with orbital interactions and the reversal of kinetic and thermodynamic selectivity.

Tuning the Fluorescence in Dynamic Covalent Bonded Liquid Crystals

ACS Applied Materials & Interfaces, 2022
A series of emissive liquid crystalline materials based on salicylidene derivatives is reported and investigated with respect to their thermoresponsive and mechanochromic properties. Single-crystal analysis and temperature-dependent powder X-ray diffraction measurements allowed us to correlate the intermolecular organization of the mesogens with ...

Dynamic Covalent Bonds in Polymeric Materials

Angewandte Chemie International Edition, 2019
AbstractDynamic covalent bonds (DCBs) have received significant attention over the past decade. These are covalent bonds that are capable of exchanging or switching between several molecules. Particular focus has recently been on utilizing these DCBs in polymeric materials.

A transient non-covalent hydrogel by a supramolecular gelator with dynamic covalent bonds

New Journal of Chemistry, 2021
In 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.

Templated Chromophore Assembly by Dynamic Covalent Bonds

Angewandte Chemie, 2015
AbstractThrough the simultaneous use of three orthogonal dynamic covalent reactions, namely disulfide, boronate, and acyl hydrazone formation, we conceived a facile and versatile protocol to spatially organize tailored chromophores, which absorb in the blue, red, and yellow regions, on a preprogrammed α‐helix peptide. This approach allowed the assembly

Covalent capture of dynamic hydrogen-bonded assemblies

Chemical Communications, 2000
Covalent linkage of the three calix[4]arene units in hydrogen-bonded assemblies 13(DEB)6via a threefold ring closing metathesis (RCM) reaction quantitatively converts the dynamic assemblies into covalent systems (123-membered macrocycles) that can be easily characterized using MALDI-TOF MS and HPLC.

H-Shaped Supra-Amphiphiles Based on a Dynamic Covalent Bond

Langmuir, 2012
The 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 ...
