A New Nanostructured Copper Schiff Base Complex: Structural and Thermal Observations

Abstract

Producing and studying two new Cu (II) Schiff base complexes: [Cu(L)₂] (ClO₄)₂ and [Cu(L)₂NO₃]NO₃ of Schiff base ligand (L=4,5,9,13,14-pentaaza-benzo[b] triphenylen). Nanostructured compounds were made using different techniques such as X-ray powder diffraction, infrared spectroscopy, scanning electron microscopy, and elemental studies. Differential scanning calorimetry (DSC) and thermal gravimetric (TGA) analyses were used to examine the thermal stability of bulk complexes and nanoparticles. By calcining the nanostructure complexes at 450°C, CuO nanoparticles were produced. In CH₃CN solution, the copper complexes provide a quasi-reversible reduction process, according to comparative electrochemical experiments.
