Abstract
AbstractThe synthesis and characterization of tetra 3,4‐dimethoxyphenethoxy substituted cobalt, zinc and copper phthalocyanines are reported. These compounds have been characterized by using electronic absorption, nuclear magnetic resonance spectroscopy, infrared spectroscopy, and elemental analysis. The aggregation behaviors were investigated in different concentrations phthalocyanine complexes. The photodegradation stabilities of pthalocyanine complexes 4–6 were determined in THF. The antioxidant activities of scavenging effect on 1,1‐Diphenyl‐2‐picryl‐hydrazyl (DPPH) radicals and ferrous chelating reducing power were also investigated. The antimicrobial effects of compounds were evaluated. In addition, DNA cleavage activities of the ligand and its phthalocyanine complexes were experimented on plasmid DNA (pBR322) using DNA gel electrophoresis and the complexes exhibited promising cleavage activity. Thermal properties of compounds were determined by thermogravimetric analysis(TG) and differential thermal analysis (DTA).
