Abstract

The (E)-4-chloro-N-(2-(dimethylamino)ethyl)-5-((8-hydroxyquinolin-5-yl)diazenyl)-2-methoxybenzamide azo ligand (L) has been synthesized through the reaction of diazonium salt for 5-amino-4-chloro-N-(2-(dimethylamino) ethyl)-2-methoxybenzamide with 8-hydroxyquinoline and identified azo ligand (L) using spectroscopic studies (FTIR, UV-Vis, ¹H and ¹³CNMR, mass), and micro-elemental analysis (C.H.N). Metal chelates of Co(II), Ni(II), Cu(II), as well as Zn(II) have been completed as well as characterized using mass spectra, flame atomic absorption, elemental analysis (C.H.N), infrared, UV-Vis spectroscopy, as well as conductivity, magnetic measurements. The metal-to-ligand ratio in all complexes, as determined by analytical data, was 1:2 and exhibited a tetrahedral structure of the prepared complexes with the ligand, as the ligand is linked to the metal ions through the N atom of the (C=N) group and the substituted OH-group, which has lost its proton to form a stable five-membered ring with the 8-hydroxyquinoline compound. Then, colors play a significant role in detergent stability and brightness during the dyeing of composite materials produced on cotton fabrics. Therefore, solid dyes exhibit excellent color stability and depth of texture.
