Synthesis characterization of new type of metal phthalocyanine complexes containing cyclododecanol group

In this work, 4-(dodecyloxy) phthalonitrile was synthesized from 4-nitrophthalonitrile and cyclododecanol under argon atmospheres. Then, 2,9,16,23-tetrakis(4-(dodecyloxy)) phthalocyanine was reacted with salts of Cu (II), Co (II), Ni(II) and (Cu, Co, Ni, Zn) complexes were obtained. Structures of the synthesized complexes were examined by FTIR, UV-visible spectrophotometer, thermal analysis methods thermo-gravimetric analysis (TGA) and differential thermal analysis (DTA). Electrochemical properties of copper and zinc phthalocyanine complexes were investigated by voltammetry, since the solubility of the complexes is very low in general organic solvents
