• The synthesis of new schiff base substituted metallophthalocyanines.
• Redox behavior of schiff base substituted metallophthalocyanines.
• Synthesize and characterization of phthalocyanines bearing schiff bases.
• Spectroelectrochemistry of schiff base substituted phthalocyanine.
• The catalytic activity of schiff base substituted phthalocyanine for mercaptan oxidation.
The synthesis and characterization of novel metallophthalocyanines (M = Zn, Co) carrying four schiff base on four peripheral positions were realized. These complexes have been characterized by a combination of FT-IR, 1H NMR, HRMS and UV–Vis spectroscopy techniques. Electronic absorption spectra showed that both Pcs are nonaggregable molecules and also well solubles common organic solvents such as dichloromethane, chloroform, THF, DMSO and DMF. Cyclic voltammograms give two reduction reaction for Pc-6 and one reduction reaction for Pc-7. The spectroelectrochemical investigation shows the ring based reduction potential for MPc's. Pc-7 cobalt(II)phthalocyanine was investigated as catalyst in the catalytic oxidation of 2-mercaptoethanol. Turnover number, initial reaction rate and the oxygen consumption was found in the catalytic oxidation of 2-mercaptoethanol as 18.6, 0.34, 2.75 respectively.
