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.

Dynamic covalent polymers: Reorganizable polymers with dynamic covalent bonds

Progress in Polymer Science, 2009
Abstract The recent research on dynamic covalent polymers is reviewed. These polymers exhibit dynamic features originating in the reversibility of dynamic covalent bonds. The main body of the review is presented in four sections: (i) utilization of dynamic covalent bonds in reactive polymer blends, (ii) ring–chain equilibrium based on dynamic ...

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.
