Synthesis and characterization of novel 2-{[2-(dimethylamino)ethyl](methyl)amino} ethoxy-substituted metallophthalocyanines

Abstract

The synthesis of novel, symmetrical, tetrasubstituted metallophthalocyanines (cobalt, zinc, and copper) bearing four 2-{[2-(dimethylamino)ethyl](methyl)amino} ethoxy units was reported. The dinitrile derivative was converted into the water-soluble quaternized product by its reaction with methyl iodide. The quaternized zinc phthalocyanine was obtained from the reaction of the water-soluble dinitrile derivative with zinc acetate. The structures of the newly synthesized molecules were proposed according to elemental analysis, 1H NMR, FT-IR, and UV-Vis spectral data.
