From β-Dicarbonyl Chemistry to Dynamic Polymers
The past two decades have witnessed an explosion of the use of dynamic bonds in polymer science. The β-dicarbonyl skeleton has emerged as a most versatile platform motif that has been utilized to synthesize a plethora of dynamic polymers that leverage either reversible metal–ligand coordination or exchangeable dynamic covalent bonds. The high modularity and intrinsic dynamic nature of the structures based on the β-dicarbonyl motif have received considerable interest across diverse fields, in applications that include drug delivery, the development of sustainable polymers, 3D printing, actuators, and many others. This review summarizes the progress on dynamic polymers derived from β-dicarbonyl synthons and focuses on three main topics. The first section provides a comprehensive overview of the prevalent methodologies employed for the preparation of polymers containing β-dicarbonyl moieties. The second part highlights the key features, development, and applications of dynamic polymers based on the β-dicarbonyl chemistry, including metallo-supramolecular polymers and dynamic covalent polymer networks. In the concluding section, we offer our views on the future challenges and prospects pertaining to this class of dynamic polymer systems.

ReHuse
Stimuli-responsive polymers adapt their properties in response to external cues. Engineering such “smart” behavior in artificial systems by molecular design is an exciting fundamental challenge that can lead to technological breakthroughs. Most stimuli-responsive polymers rely on heat and light to trigger changes in materials properties in a predictable fashion. However, limitations intrinsic to these stimuli highlight the necessity of alternative strategies. Naturally evolved systems widely exploit mechanical stimulation to regulate their functions, but recreating such concept in artificial materials has proven extremely challenging thus far.

ForcING
ForcING is a research project operating within the context of polymer mechanochemistry, a two-decade old research field that studies how mechanical forces propagate at the molecular level within polymeric materials. Key chemical substances for this type of study are mechanophores, species that are sensitive to mechanical forces and produce physicochemical responses as a result of mechanical stimulation. Thus, mechanophores serve the function of force sensors through which we can infer about the mechanical state (and mechanical history) of a material. Despite the tremendous progress obtained in the past two decades, polymer mechanochemistry is still far from having a moleculardetailed knowledge about mechanophores activation.
