咪唑鎓大环的研究进展
Progress in imidazolium macrocycles
摘要
近年来，不同空腔大小的咪唑鎓大环不断地被设计合成。咪唑鎓本身带正电荷，含有较高酸性的二位碳氢，不仅能够与阴离子形成氢键作用，而且易失去质子变成咪唑卡宾。因此，咪唑鎓大环不仅可以识别各种无机阴离子和生物体内重要的阴离子，而且能够应用于金属卡宾催化和超分子组装方面。本文综述了咪唑鎓大环在过去十余年来的研究进展，并按照环空腔大小和咪唑鎓个数详细阐述了咪唑鎓大环的合成、性质及应用。
Abstract
In recent years, various imidazolium macrocycles with different cavities have been designed and synthesized. The imidazolium moiety provides both a positive charge and relatively acidic C2-hydrogen which not only can bind anionic targets by hydrogen bonding interactions, but also can form imidazole carbenes by losing a proton. Therefore, imidazolium macrocycles can recognize a variety of inorganic anions and physiologically important anions and are also applied to the area of carbene catalysis and supramolecular assembly. In this paper, the development of the imidazolium macrocycles in the past decade are reviewed and their synthesis, properties and applications are discussed according to the cavity size and the number of the imidazolium moiety.关键词
