Click chemistry in polymer science

Click Chemistry in Lithium‐Metal Batteries

“…Comfortingly, click chemistry is a synthetic method allowing near‐quantitative postpolymerization modification, and this feature is particularly advantageous for building SEI layers. [ 91 ] The fabrication process of artificial SEI layers is usually conducted following the in situ methodology, which means there is no scope for further purification of the product. Hence, compared with the click reactions used for PEs’ preparations, the SEI layers’ construction process requires more precise design and regulation.…”

In Situ Construction of Polymer Electrolytes with Dynamic Covalent Networks via Initiator-Free Thiol-Methacrylate Radical Polymerization

“…16,17 As a versatile chemical toolbox, click chemistries, including azide− alkyne cycloaddition, 18 Diels−Alder reaction, 19 and thiol chemistries, 20 have been widely applied in all disciplines of chemistry. 21 Among them, the thiol−ene reaction is frequently utilized in the preparation of polymers due to its simplicity and effectiveness. 15,20,22 Generally, the thiol−ene reaction is either an initiator-induced radical reaction or an alkali-catalyzed Michael addition reaction.…”

“…To manufacture PEs via in situ polymerization, an appropriate polymerization rate and avoidance of extraneous components (initiators or catalysts) are essential. , As a versatile chemical toolbox, click chemistries, including azide–alkyne cycloaddition, Diels–Alder reaction, and thiol chemistries, have been widely applied in all disciplines of chemistry . Among them, the thiol–ene reaction is frequently utilized in the preparation of polymers due to its simplicity and effectiveness. ,, Generally, the thiol–ene reaction is either an initiator-induced radical reaction or an alkali-catalyzed Michael addition reaction. , However, in situ polymerization via the thiol–ene reaction inevitably requires a radical initiator or catalyst, which adversely affects the cycling stability of lithium-based batteries. , Meanwhile, the introduction of solvents is not conducive to the continuous assembly of batteries.…”

Light Harvesting Modulation of Melanin-Like Polymers via Thiol-Michael “Click” Chemistry

“…“Click” chemistry has been regarded as a chemical philosophy and was awarded the Nobel Prize in 2022, which includes a series of orthogonal and highly efficient reactions with rapid process, high yield, and stable products under mild conditions. − It has achieved breakthrough in constructing and engineering macromolecular materials with well-defined structures, such as digital polymers , and peptide biomimics. , In addition, “click” reaction also plays important roles in structural-chaotic materials, such as enabling the efficient preparation, modification, and purification of complex polymer architectures …”
