Bis-(quinolin-8-ylmethyl)-substituted Diaza-18-crown-6: Synthesis and Metal Ion Complexation Properties

Abstract

N,N-Bis-(quinolin-8-ylmethyl)diaza-l 8-crown-6 (L) was prepared in a high yield by treating diaza-18-crown-6 with 8-bromomethylquinoline in the presence of triethylamine. Ligand L interacted strongly with Na(+), K(+), Mg(2+), Co(2+), Cu(2+), Ni(2+), and Zn(2+) as shown by calorimetric titration and UV-Visible spectrophotometric techniques. The ligand exhibited a good selectivity for Cu(2+) over Ni(2+). The calorimetric titration indicated that ligand L forms both mononuclear and binuclear complexes with Cu(2+).
