In this study, a new porphyrin-Schiff base ligand (L) and its metal complexes (Cu(II), Fe(III), Mn(III), Pt(II) and Zn(II)) were synthesized. The starting material 4-ethyl-2,6-bis(hydroxymethyl)phenol (A) was synthesized from 4-ethylphenol and formaldehyde in the alkaline media. The compound (A) was then oxidized to the 4-ethyl-2,6-diformylphenol (B). The starting compounds (A) and (B) were obtained as single crystals. Structures of the compounds (A) and (B) were determined by the X-ray crytallography technique. The porphyrin ligand (L) and its metal complexes were characterized by the analytical and spectroscopic methods. Electronic, electrochemical and thermal properties of the synthesised compounds were investigated. Superoxide dismutase activities (SOD) of the porphyrin Schiff base complexes were investigated and results were discussed. Additionally, the DNA (fish sperm FSdsDNA) binding studies of the complexes were performed using UV-vis spectroscopy. Competitive studies with ethidium bromide (EB) show that the compounds interact efficiently with DNA through an intercalating way. © 2015 Elsevier B.V. Source
