Synthesis and Hg2+-Selective Ionophoric Properties of p-tert-Butylcalix[4]arene-aza-crown Ethers

A series of new p-tert-butylcalix[4]arene aza-crown ethers has been prepared. They showed pronounced selective ionophoric properties in transport experiments toward Hg2+ ions among the heavy metal ions and Cu2+ ions among the transition metal ions surveyed. The calix[4]arene diaza-crown ethers are f...

Description
Summary:A series of new p-tert-butylcalix[4]arene aza-crown ethers has been prepared. They showed pronounced selective ionophoric properties in transport experiments toward Hg2+ ions among the heavy metal ions and Cu2+ ions among the transition metal ions surveyed. The calix[4]arene diaza-crown ethers are found to be relatively well optimized for the transport of Hg2+ ions.
