中文摘要：
概述了冠醚的结构特征及其分类;重点介绍了近几年合成冠醚常用的两种方法：末端活性基团逐步反应成环法和直接侧链化方法;综述了冠醚类表面活性剂的独特性质;最后,对冠醚型表面活性剂在有机合成、生物膜体系、感光材料、离子选择电极中的应用做了阐述,并对其今后的研究方向及发展趋势进行了展望。
英文摘要：
The structural characteristics and classification of crown ether were briefed.Particular attention was given to the two kinds of method used in synthesis of crown ether,the gradual cyclization method and the side chain direct formation method.Unique properties of crown ether surfactants were reviewed.Finally,the applications in organic synthesis,creation of biological membrane systems,preparation of photo-sensitized materials and ion selective electrode were discussed.Meanwhile,the development of crown ether surfactants in the future was prospected.
