Synthesis, Transport, and Ionophoric Properties of α,ω-Diphosphorylated Azapodands: XI. Membrane Transport of Metals by Phosphorylated Diazapodands

Abstract

© 2018, Pleiades Publishing, Ltd. The membrane transport of rare-earth metals and scandium by new diphosphorylated diazapodands was studied. It was found that the introduction of butyl groups and an additional phosphoryl group on the nitrogen atoms of the terminal aminomethylphosphinoyl groups of azapodands decreases the efficiency of transport of rare-earth metals and increases the selectivity to scandium ion.
