Özet

The electrochemical characterization and synthetic procedures of novel metallophthalocyanines (Co, Cu and Mn) 5, 6 and 7 fused eight N-(2,3-dihydro-1,5-dimethyl-3-oxo-2-phenyl-1H-pyrazol-4-yl)-4-methyl-benzenesulfonamide groups connected to ethylmercapto arms on peripherally positions were reported in this work. The metal complexes 5, 6 and 7 were prepared by a tetramerization reaction of the phthalonitrile derivative 4 with corresponding metal salts and materials. The characterization of new products was made by a combination of elemental analysis, FT-IR, MALDI-TOF mass spectral data, UV-Vis, H-1 NMR and C-13 NMR. Electrochemical characterization of metallophthalocyanines was determined by using cyclic voltammetry (CV) and square wave voltammetry (SWV) techniques. Copper(II) phthalocyanine showed Pc based electron transfer processes because of redox inactive metal center. On the other hand, Mn-III and Co-II metal ions behave as redox active cations in the core of the phthalocyanines. Therefore, (MnClPc)-Cl-III and (CoPc)-Pc-II gave metal and ligand based reduction reactions as expected. (C) 2017 Elsevier B.V. All rights reserved.
