报告介绍

Dynamic polymers are a class of polymers cross-linked by reversible, (non-)covalent bonds. The past two decades have witnessed the development of a wide array of reversible chemical motifs, which ultimately led to the establishment of a large scope of dynamic polymer materials. Among these motifs, the β-dicarbonyl skeleton has emerged as a modular platform to synthesize dynamic polymers leveraging either metal-ligand coordination or exchangeable covalent linkages via dynamic covalent chemistry. The high modularity and intrinsic dynamic nature of the β-dicarbonyl motif have garnered considerable interest across diverse fields, such as drug delivery, development of sustainable polymers, 3D printing, and actuators. In this talk, I will present the dynamic bonds derived from β-dicarbonyl synthons, including metal-β-dicarbonyl coordination bonds, vinylogous urethane, hydroxylketoenamide, aminoketoenamide, and β‐(1,3‐dioxane) ester. This is accompanied by the elaboration of the structure–property relationships of corresponding dynamic polymers, synthesized by direct polymerization, post-polymerization modification, or cross-linking of small molecules, commercial polymers, and even food protein waste. The related chemistry and materials knowledge then catalyze the application of these polymers in several fields, with the examples of chemical re-/up-cycling, food packaging, and wearable sensors, among others, which will be introduced as well.  The final part provides my view on the future challenges and prospects pertaining to this class of dynamic polymer systems.
