Özet

In this work, 2-{[5-(4-chlorophenyl)-4-ethyl-4H-1,2,4-triazol-3-yl]thio}ethanol have been firstly synthesized and characterized to prepare 4-{[5-(4-chlorophenyl)-4-ethyl-4H-1,2,4-triazol-3-yl]thio}phthalonitrile and then finally 1,2,4-triazol substituted Co(II) and Cu(II) phthalocyanine. All compounds have been characterized with FT-IR (Fourier transform infrared spectroscopy), UV-Vis (UV-Visible Spectrophotometer), 1H-NMR (1H-Nuclear Magnetic Resonance), 13C-NMR (13C-Nuclear Magnetic Resonance) and mass specta. 4-Nitrophenol (4-NP) oxidation reaction have been chosen among organic pollutants to investigate photocatalytic potential of Co(II) and Cu(II) phthalocyanine. While both complexes showed high product selectivity, Cu(II) phthalocyanine also showed high product conversion. Oxidant type, oxidant amount effects and photodegradation studies have also done at room temperature in 15 min.
