Özet

A soluble metal-free phthalocyanine 5 and its metal complexes (Zn, Ni, Co and Cu) 6, 7,8 and 9 containing eight 16-membered tetrathiamonoaza. macrocycles on peripheral substituent positions have been synthesized. The metal-free phthalocyanine 5 was synthesized from 4,5-bis{[2-(1,4,10,13-tetrathia-7-azacy-clohexadecan-7-yl)ethyl]oxy}phthalonitrile 4. The metal complexes 6, 7 and 8 were prepared by a tetramerization reaction of the phthalonitrile derivative 4 with appropriate materials. Copper(II) phthalocyanine 9 was prepared by the reaction of 4,5-bis{[2-(1,4,10,13-tetrathia-7-azacyclohexadecan-7-yl)ethyl]oxy}-1,2-dibromobenzene 3 with excess CuCN and dry quinoline. Liquid-liquid extraction of several heavy metal ions such as Ag(+), Hg(2+), Pb(2+), Cd(2+), Cu(2+) and Zn(2+) with compound 5 was also tested using picrate as the anion of the ion pair. The extraction avidity of 5 for Ag(+) was found to be highest in the liquid-liquid phase extraction experiments. The new compounds were characterized by a combination of elemental analysis, UV-Vis, FT-IR, NMR and mass spectral data. (C) 2008 Elsevier Ltd. All rights reserved.
