Emission-Tunable Amorphous Room-Temperature Phosphorescent Polymers Based on Thermoreversible Dynamic Covalent Bond.

Angewandte Chemie, 2020
Pure organic room-temperature phosphorescence (RTP) materials are useful for photoelectric, biochemical devices and bioimaging sensors. In the last few years, dynamic covalent chemistry has aroused substantial attention as it offers a way to create ...

pH-Responsive Non-Pickering Emulsion Stabilized by Dynamic Covalent Bond Surfactants and Nano-SiO2 Particles.

Langmuir, 2020
A novel stimulus-responsive non-Pickering emulsion stabilized by nano-SiO2 particles was prepared in our recent study. 4-formylbenzoic acid and hexylamine through a dynamic covalent bond form a surface-active substance, which was confirmed by Fourier ...

Switching biological functionalities of biointerfaces via dynamic covalent bonds

Journal of Materials Chemistry B, 2016
We construct a stimuli responsive biointerface via a dynamic covalent bond that could switch its surface biofunctionalities on demand. The switchability is achieved via reversible attaching/detaching of aldehyde end-functionalized biomacromolecules.

Effects of dynamic covalent bond multiplicity on the performance of vitrimeric elastomers

, 2020
It is still a challenge to integrate multiple dynamic covalent bonds (DCBs) into one network, so the effects of DCB multiplicity on the performance of covalent adaptable networks (CANs) are still unclear. In this contribution, based on the versatility of

Use of Bis(2,2,6,6-tetramethylpiperidin-1-yl)trisulfide as a Dynamic Covalent Bond for Thermally Healable Cross-Linked Polymer Networks

, 2020
Dynamic covalent bonds (DCBs), which can undergo reversible cleavage and reformation upon exposure to readily useable stimuli, have attracted dramatic attention, but the library of such bonds still...

Structural Properties Covalent Organic Frameworks (COFs): From Dynamic Covalent Bonds to their Applications

ChemistrySelect, 2022
Abstract Covalent organic frameworks (COFs) are classified as lightweight, ordered, porous organic polymeric compounds. COF‐based materials are comprised of the covalent bonds of lightweight elements, such as C, B, O, Si, and N, with structural units. They can be used in various industrial applications.

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.

Hydrogen‐Bond Catalysis of Imine Exchange in Dynamic Covalent Systems

Chemistry – A European Journal, 2020
AbstractThe 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.

Silane catecholates: versatile tools for self-assembled dynamic covalent bond chemistry.

Chemical Communications, 2019
Shape-persistent macrocycles and 3D nanocages have been prepared in one-pot under MeCN-promoted dynamic covalent bond conditions starting from silane catecholates, whose structures were confirmed by X-ray crystallography.
