Özet

The synthesis, characterization, spectral, antioxidant and antibacterial properties of dimethyl 5-(phenoxy)-isophthalate substituted Zinc, Cobalt, Copper, and Nickel phthalocyanines are reported. The novel compounds have been characterized by using electronic absorption, nuclear magnetic resonance spectroscopy, infrared, elemental analysis and mass spectrometry. The antioxidant and antibacterial activities of newly synthesized phthalocyanines and its starting material are tested. The DPPH free radical scavenging ability of phthalocyanine Co(II) and Zn(II) complexes on DPPH are 44.8% and 40.1% at 100 mg/L concentration, respectively. The phthalocyanine Co(II) and Cu(II) complexes show very strong ferrous ion chelating activity of 91.2% and 89.3% at concentration of 100 mg/L, respectively. Compound 3 displays strong reducing power like alpha-tocopherol. Antibacterial activities of phthalocyanine Co(II) and Amikacin (30 mu g/disk) against Micrococcus luteus (ATCC 9341) are 16 mm in diameter. (C) 2014 Elsevier B.V. All rights reserved.
