✦ Synopsis
N,N,N′,N′‐Tetrabutyl‐3,6‐dioxaoctane‐dithioamide, an Ionophore with Selectivity for Cd^2+^
The dioxa‐dithioamide 3 behaves as a highly selective ionophore for Cd^2+^ in solvent polymeric membranes. It induces cation‐permselectivity in these membranes with a transference number of 1 for Cd(NO~3~)~2~‐ and of 2 for CdCl~2~‐solutions. In the presence of a proton carrier, 3 may be used to selectively pump Cd^2+^ through membranes by coupling with a pH gradient.
