    X‐yne click polymerization
    Wiley ; 2023
    In:  Aggregate
    Details
    In: Aggregate, Wiley
    Abstract: Alkyne‐based click polymerizations have been nurtured into a powerful synthetic technique for the preparation of new polymers with advanced structures and versatile properties. Among them, the emerging thiol‐yne, hydroxyl‐yne, and amino‐yne click polymerizations have made remarkable progress from reactions to applications. These polymerizations avoid the usage of inherently dangerous monomers and are safer to operate than the classical azide‐alkyne click polymerization (AACP), making them more prospective for diverse applications. To greatly promote the new alkyne‐based click polymerizations beyond AACP, a new concept of “X‐yne click polymerization” is proposed to unify them, where “X” denotes the monomers that can react with alkynes under mild reaction conditions, including thiols, alcohols, amines, and other promising ones. In this review, we mainly present a brief account of the progress of X‐yne click polymerization and discuss in detail the challenges and opportunities in this field.

    Autonomous Visualization of Damage in Polymers by Metal‐Free Polymerizations of Microencapsulated Activated Alkynes
    Wiley ; 2022

    Abstract: The development of autonomous materials with desired performance and built‐in visualizable sensing units is of great academic and industrial significance. Although a wide range of damage indication methods have been reported, the “turn‐on” sensing mechanism by damaging events based on microcapsule systems, especially those relying on chemical reactions to elicit a chromogenic response, are still very limited. Herein, a facile and metal‐free polymerization route with an interesting reaction‐induced coloration effect is demonstrated. Under the catalysis of 1,4‐diazabicyclo[2.2.2]octane (DABCO), the polymerizations of difunctional or trifunctional activated alkynes proceed very quickly at 0 °C in air. A series of polymers composed of stereoregular enyne structure (major unit) and divinyl ether structure (minor unit) are obtained. Both the catalyst and monomers are colorless while the polymerized products are deep‐colored. This process can be applied for the damage visualization of polymers using the microencapsulation technique. Microcapsules containing the reactive alkyne monomer are prepared and mixed in a DABCO‐dispersed polymer film. Both the external and internal damage regions of this composite film can be readily visualized once the reaction is initiated from the ruptured microcapsules. Moreover, the newly formed polymer automatically seals the cracks with an additional protection function.

    Smart aggregation‐induced emission polymers: Preparation, properties and bio‐applications
    Wiley ; 2023

    In: Smart Molecules, Wiley, Vol. 1, No. 1 ( 2023-06)
    Abstract: Owing to the outstanding photophysical properties, organic luminescent materials featuring aggregation‐induced emission (AIE) characteristics have attracted wide attention in various fields. Numerous researches focused on low‐mass AIE luminogens, and relatively less attention has been paid on AIE polymers and the related applications, in spite of the fact that AIE polymers exhibit excellent advantages of processability, multifunctional integration and synergistic effects. In this review, we briefly summarize and discuss the superiorities of AIE polymers in preparation, properties and bio‐applications, and the considerable progress in these aspects are introduced as well. Finally, the structure‐property relationship, challenges and opportunities are also discussed. Hopefully, this review will be a trigger for smart AIE polymer research and further broaden their applications.

    Abstract: Isocyanide is an important class of active synthon with a special electronic structure and abundant chemical properties, which can participate in various organic reactions and has a wide range of applications in the efficient synthesis of pharmaceutical molecules, heterocyclic compounds, and natural products, etc. With the development of chemical science, isocyanide‐based reactions have been gradually applied from the synthesis of low mass molecules to functional polymers. This review focuses on the recent progress in isocyanide‐based step‐growth polymerization, as well as the properties and applications of the resultant functional polymers. These polymerizations are divided into six main parts including Passerini polymerization, Ugi polymerization, multicomponent polymerization (MCP) of isocyanide and dialkylacetylenedicarboxylates (DAADs), MCP of isocyanide and green monomer, MCP of isocyanide and industrial waste, as well as the polymerization based on isocyanoacetate. The existing challenges and the promising opportunities are concisely discussed.

    Dynamic covalent polymers generated from X ‐yne click polymerization
    Wiley ; 2023
    In:  Journal of Polymer Science
    Details
    In: Journal of Polymer Science, Wiley
    Abstract: Dynamic covalent polymers have gained more and more attention for their fascinating dynamic features and broad application prospects. As an emerging and powerful synthetic tool, X‐yne click polymerization, mainly including thiol‐yne, amino‐yne and hydroxyl‐yne click polymerizations, has been rapidly developed and widely applied in the preparation of functional polymers in recent years. Moreover, dynamic exchange processes have been successively observed in different X‐yne adducts, and then several dynamic covalent polymers have been obtained by X‐yne click polymerization. The combination of these two aspects not only provides a highly efficient synthetic approach for dynamic covalent polymers, but also further expands the application scope of X‐yne click polymerization, achieving a win–win situation. In this review, we sort out the dynamic exchange mechanisms based on the formation of β ‐heteroatom enolate intermediates and give a detailed account of the progress of dynamic covalent polymers generated from X‐yne click polymerization and their applications in covalent adaptable networks (CANs), self‐healing injectable polymer hydrogels and functional porous polymeric films, etc. The existing deficiencies and future prospects in this field are also discussed.
