A novel n-pivot macrocyclic ligand and its Cobalt(II) phthalocyanine derivative: synthesis, characterization and extractant properties

A novel n-pivot macrocyclic ligand and its Cobalt(II) phthalocyanine derivative: synthesis, characterization and extractant properties

In this study, the synthesis of a novel N-pivot 12-membered macrocyclic ligand with mixed donor atoms 2, which is a phthalonitrile derivative, and a new cobalt(II) phthalocyanine complex 3 obtained by cyclotetramerization reaction of  2 were described.  Newly synthesized compounds were characterized by using several spectroscopic techniques such as IR, UV-Vis, 1H and 13C NMR, MS and elemental analysis. These macrocyclic systems 2 and 3 were investigated as extractants in liquid-liquid extraction technique to reveal metal ion binding capability towards transition metals such as Ag(I), Hg(II), Cd(II), Zn(II), Cu(II), Ni(II), Pb(II) and Co(II). The highest extractability from aqueous phase to organic phase was found for Hg(II) cation over the other metal cations with cobalt(II) phthalocyanine 3. The extraction percentage of Hg(II) cation from aqueous phase to chloroform in the presence of cobalt(II) phthalocyanine 3 as extractant was found as 96.0%.
