近年来,含腙(—CH N—NH—)结构单元的阴离子识别主体的设计、合成及应用成为超分子阴离子识别领域研究的热点之一。此类主体具有结构丰富、可调节性强、识别范围广、选择性强、灵敏度高等优点。本文综述了含腙及酰腙为识别基团的阴离子主体的设计原理、识别性能和机理,展望了该领域的发展方向。
In recent years, the design, synthesis and application of anionic recognition groups containing hydrazone (-CH N-NH-) structural units have become one of the hot topics in the field of supramolecular anion recognition. Such main body has the advantages of rich structure, strong adjustability, wide recognition range, strong selectivity and high sensitivity. In this paper, the design principle, recognition performance and mechanism of anion groups containing hydrazones and acylhydrazones as recognition groups are reviewed. The development direction of this field is also expected.
