Analysis of the Possibility of the Crown Ether Structure Modification by the Introduction of Chelate Fragment

Alyona Igorevna Wozniak and Anton Sergeyevich Yegorov



This paper describes the basic selectivity principles of polydentate ligands. There were considered choices of structure modification of crown ethers to enhancetheir complexing properties. There was compared a complexstability and the selectivity of the various metal cations of oxygen-containingcrown ethers with the nitrogen-containing crown ethers.
