Optoelectronic, Photocatalytic, and DNA interaction studies of synthesised Cu(II), Co(II), and Ni(II) complexes containing schiff base ligand

An innovative, active Cu(II), Co(II), and Ni(II) complexes of Azomethine ligand [5-(diethylamino)-2-hydroxyphenyl]methylidene}benzo hydrazide] were synthesized. The afresh made ligand and its metal complexes were premeditated by elemental analysis, FT-IR, UV-Visible, H-1 & C-13 NMR, LC-MS spectroscopy, and X-ray powder diffraction. The Optimized structure of the compounds was done by Density Functional Theory (DFT) in Gaussian09 program at the basis set RB3LYP at 6-311G (++, g, d, p). The PL emission of the metal complexes was tuned in the Ultraviolet region, which concluded that it is shown that the metal layer leads to an enhanced photoluminescence efficiency of metal complexes. The redox behavior of the metal complexes was investigated by the cyclic voltammetry technique. Photocatalytic results related degradation of Malachite green indicated that the metal complexes dramatically enhance the catalytic activity. This means that metal complexes showed virtuous photocatalytic activity under UV light irradiation. Further, the metal complexes have also shown significant DNA binding with CT-DNA and pUC-19 DNA cleavage activities.

Automated summary

The study synthesized active Cu(II), Co(II), and Ni(II) metal complexes with an azomethine ligand, and characterized their structures and properties using various analytical techniques. The metal complexes exhibited excellent photocatalytic activity and DNA binding ability.
