摘要
本文总结了近年来阴离子荧光受体的研究进展和荧光化学传感的主要机理 ,主要介绍以下 3类受体的设计合成及其在阴离子识别中的应用 :(1)以氢键或静电作用键合阴离子的受体 (包括酰胺、脲及硫脲、胍盐和硫脲盐、五员杂环 ) ;(2 )含金属和路易斯酸的受体 ;(3)以竞争键合机制识别阴离子的“化学传感体系”
The latest research progress in fluorescent receptors for anions and common mechanisms in sensing is summarized. The design, synthesis and application of three types of anion receptors are reviewed: (1) receptors based on hydrogen bonding or electrostatic interactions containing amide I urea, thiourea. guanidinium, thiouronium, or five-member heterocycle groups; (2) receptors consisting of metal or Uwis acid center; (3) chemosensing ensemble based on competitive bonding mechanism.
