Abstract:
冠醚(Crown Ethers)是一类具有特定环状空腔结构的化合物，从较小的环到较大的多环结构都有(如14-冠-4醚、15-冠-5醚、18-冠-6醚等等)，这种特殊的环状结构和尺寸大小赋予了冠醚独特的物理和化学性质，其独特的离子识别能力为高效离子分离提供了新的解决方案。本文综述了冠醚功能化多孔材料(包括金属有机框架MOFs、共价有机框架COFs、介孔二氧化硅MS)的设计原理、实验结果分析及其在相关领域的应用进展和未来发展方向。
Crown ethers are a class of compounds with specific cyclic cavity structures, ranging from smaller rings to larger polycyclic structures (such as 14-crown-4 ether, 15-crown-5 ether, 18-crown-6 ether, etc.). This special cyclic structure and size give crown ether unique physical and chemical properties, and its unique ion recognition ability provides a new solution for efficient ion separation. In this paper, the design principles, experimental results and application progress and future development direction of crown ether functionalized porous materials (including metal-organic framework MOFs, covalent organic framework COFs, and mesoporous silica MS) are reviewed.
