Synthesis, Characterization and Thermal Behavior of New Bis- Metallophthalocyanines (Cu, Co, Zn, Ni) and Bis-Metal Free Phthalocyanine

Abstract

In this work, a novel bis-metallophthalocyanines Cu(II) (4), Co(II) (5), Zn(II) (6), Ni(II) (7) and bis-metalfreephthalocyanine (8) have been synthesized from 4,4'-(2-methyl-1,4-phenylenedioxy)diphthalonitrile (3), which can be obtained by the reaction of 4-nithrophthalonitrile (2) with 2-methylhydroquinone (1). Compound 3 has been characterized by elemental analysis, FT-IR, ¹H-NMR and ¹³C-NMR spectroscopies. 4-8 bis-phthalocyanine compounds have been characterized by the elemental analysis, UV/Vis, and FT-IR spectroscopies. The thermal properties of the bis-phthalocyanine compounds were examined by Thermogravimetric Analysis (TGA) and Differential Thermal Analysis (DTA). TGA results showed that bis-phthalocyanine compounds have been thermal stability untill 320- 410° C
