| Popis: | The present paper presents the obtaining and the characterization of a new complex acid dye by combining the transition metal Cu (II) with an azo acid dye, namely Amido Black 10B (C.I. 20.470), as ligand. The ligand and the resulted new azo complex were characterized by FT/IR spectroscopy, UV-Vis spectroscopy, AAs spectrometry, thermal analysis, and PXRD spectrometry. The structure of the ligand and the structure of the new synthesized copper complex were elucidated by all the above mentioned analysis methods. The formation of the azo metal complex with Cu(II) was confirmed by UV-Vis spectrum. Thermogravimetric and spectral analysis reveal its different stability in the air and nitrogen atmosphere, with high nitrogen stability. The PXRD analysis shows crystalline structure for the copper complex. At the same time, the color analysis was performed for the ligand and the synthesized complex in powder by means of UV-Vis CIEL*a*b* color space parameters, under the CIE recommended illuminants: D65 (natural day light), A (incandescent light) and F2 (fluorescent light) under the standard 10� observer angle. An important color phenomenon, namely metamerism, was highlighted for the complex, as well. Due to the presence of the Cu (II) ions, this azo complex presents a different color, calculated by the color differences AE*ab and AC*, a superior saturation and color strength than its ligand. |
