3,7-Dioxaazelaamides as Ionophores for Lithium Ion Selective Liquid Membrane Electrodes
Lipophilic neutral carriers were synthesized which show Li+/Na+ selectivities of up to ca. 80 in highly lipophilic liquid membranes.The sensor membranes exhibit improved response times and increased lifetimes as compared to systems d
