摘　　要：自动态共价键概念问世以来,含硫动态高分子作为动态化学中的一类重要高分子在化学、生物、材料等领域的应用取得了重大进展。硫元素作为自然界中常见元素,其来源广泛,且理化性质较为活泼,可参与多种有机化学反应,因此含硫动态高分子得到了迅速发展。本文介绍了不同类型的含硫动态共价键,简述了其动态影响因素,并探讨了多种含硫动态共价键在高分子材料设计和构建中的应用,特别是对材料化学、电子器件、生物医疗等领域的影响,最后对含硫动态高分子材料的未来发展作了展望。Since the concept of dynamic covalent bonding was introduced,sulfur-containing dynamic polymers,as an important class of polymer in dynamic chemistry,have made breakthroughs in many fields such as chemistry,biology,and materials.The rapid development of sulfur-containing dynamic polymers is attributed to the various fascinating properties of elemental sulfur.Sulfur,as a common element in nature,is related to biological origins and essential to biological metabolism,such as sulfur in DNA and amino acids.Sulfur exists widely in nature,such as sulfur in crude oil,and sulfide ores in the geological environment.Sulfur-containing compounds are more active and diverse in physicochemical properties and participate in a variety of organic chemical reactions.In this review,different types of sulfur-containing dynamic covalent bonds(e.g.,dynamic disulfide bonds,dynamic thioester bonds,dynamic thioacetal bonds,dynamic thiosemicarbazone bonds,and some unusual sulfur-containing dynamic bonds)are described.The effects of the reaction conditions and the chemical structure on the dynamic behaviors are briefly summarized.The mechanisms of dynamic behaviors of some sulfur-containing dynamic polymers are analyzed.In addition,the applications of various sulfur-containing dynamic covalent bonds to polymer design and applications in the fields of materials chemistry,electronics,and biomedicine are introduced.Finally,the current difficulties and challenges in the development of sulfur-containing dynamic polymer materials are analyzed,and an outlook on their future development is given.
