Optoelectronic, photocatalytic and biological studies of mixed ligand Cd(II) complex and its fabricated CdO nanoparticles

This existing examination focuses on the synthesis of the novel Azo-imine ligand obtained from the simple condensation of 2-hydroxy-3-methoxy benzaldehyde with 4-amino-azobenzene and its Mixed ligand Cd(II) Complex was synthesized using Azo-imine ligand as primary ligand and 8-hydroxy Quinoline as a secondary ligand in the equimolar ratio. Further, the obtained complex was fabricated as CdO through the thermal decomposition method. The obtained compounds were illuminated by the different spectroscopic techniques and the formation of the nanoparticles was confirmed by Powder-XRD and TEM Analysis. The CV and PL properties of the synthesized compounds have been investigated in different conditions. Photoemission wavelength at 481 nm and 498 nm specified that both Cd(II) complex and CdO enhance strong Blue luminescence on photoemission. From the electrochemical studies, the reduction of Cd(II) was found to be Quise-reversible in a 0.1 M KOH and give evidence for the formation of a mixed ligand Cd(II) complex in the molar ratio 1:1:1. For Acid red dye under Visible light, CdO shows effective photodegradation than the mixed ligand Cd(II) complex. The DNA Binding study of mixed ligand Cd(II) complex with CT-DNA was investigated by the absorption spectroscopy method and the results gave the evidence for the classical intercalation. The DNA Cleavage results are the indication that the metal complex has good costs in the cleavage of pUC-18 DNA. Further, the antibacterial study of the compounds shows satisfactory results against Gram-positive ( Staphylococcus Aureus) and Gram-negative (Proteus) bacterial strains. (c) 2021 Elsevier B.V.
