Hydrogels have been widely used in many fields. To meet the application requirements of different fields, hydrogels with different functions have been developed through efficient organic reactions. Multicomponent reactions (MCRs) have been used as distinct tools in hydrogel preparation, owing to their high efficiency, mild reaction conditions and tolerance for various functional groups. In this mini-review, we present a comprehensive overview of the roles of MCRs as crosslinking reactions and as functional group introducers in hydrogel construction. Finally, we will discuss the future perspectives of MCRs in exploring (multi)functional hydrogels.

通过多组分反应构建的水凝胶


水凝胶已广泛应用于许多领域。为了满足不同领域的应用要求，通过高效的有机反应开发了具有不同功能的水凝胶。多组分反应 （MCR） 因其高效、温和的反应条件和对各种官能团的耐受性而被用作水凝胶制备中的独特工具。在这篇小型综述中，我们全面概述了 MCR 在水凝胶构建中作为交联反应和官能团引入剂的作用。最后，我们将讨论 MCRs 在探索（多）功能水凝胶方面的未来前景。
