Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II), is researched, Molecular C48H38CoN4O4, CAS is 28903-71-1, about Spectroscopic, Electrochemical, Magnetic and Structural Characterization of an Hexamethylenetetramine Co(II) Porphyrin Complex – Application in the Catalytic Degradation of Vat Yellow 1 dye.Quality Control of 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II).
In this study, a new cobaltous-(hexamethylenetetramine) [meso-tetra(para-methoxyphenyl)porphyrin complex] with the formula [CoII(TMPP)(HMTA)] (1) was synthesized. The mol. structure was confirmed in solution by 1H NMR spectroscopy and mass spectrometry methods, and the single crystal x-ray diffraction structure of 1 was determined at both room temperature and low temperature This species was further characterized by IR, UV-visible and fluorescence spectroscopies, magnetic susceptibility measurements and cyclic voltammetry. The chem. reactivity behavior was also assessed theor. through D. Functional Theory (DFT) approach. Magnetic investigation indicates that the Co(II)-HMTA porphyrin 1 species at low temperature is a cobaltous low-spin (S = 1/2) species while at high temperature complex 1 exhibits a spin-crossover low-spin (S = 1/2) ↔ high-spin (S = 3/2). The adsorption kinetic of the “”vat yellow 1 dye”” was carried out in aqueous solution at pH = 6. The exptl. results are better fitted using the pseudo second order model. Furthermore, complex 1 was tested as catalyst in the degradation of the vat yellow 1 dye using an aqueous H2O2 solution and by photodegradation under solar light.
As far as I know, this compound(28903-71-1)Quality Control of 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II) can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
