摘　　要：冠醚作为第一代大环主体分子,具有柔性的空腔,因其对金属离子、有机阳离子的络合作用而被广泛用于构筑超分子组装体。磺化冠醚是一种水溶性良好的阴离子型冠醚衍生物,相比于冠醚,它具有更多的键合位点,对金属离子、有机阳离子具有更强的键合和良好的选择性。本文从磺化冠醚的合成,对碱金属离子、镧系金属的络合,对有机阳离子客体的组装等方面介绍了磺化冠醚的研究进展。然后从热力学、晶体结构学的角度综合分析了磺化冠醚键合与组装的模式及驱动力。最后讨论了磺化冠醚的分子键合与组装发展所面临的挑战,并对其应用前景进行了展望。Crown ethers,as the first generation macrocycle,with flexible cavity,are widely used to construct supramolecular assemblies,due to their complexation of metal ions and organic cations.Sulfonated crown ether is a kind of anionic crown ether derivative with good water solubility,compared with crown ether,it possess more binding sites,stronger binding ability and better guest selectivity with metal ions and organic cations.This review introduces the research progress of sulfonated crown ether from the synthesis of sulfonated crown ethers,the complexation of alkali metal ions,lanthanide metals,and the assembly of organic cationic guests.Then we comprehensively analyse the binding modes and driving forces of sulfonated crown ethers from the perspectives of thermodynamics and crystal structures.Finally,we discuss the opportunities and challenges of the development of molecular binding and assembly of sulfonated crown ethers,and prospected the application of sulfonated crown ethers.
