| Résumé : |
This doctoral thesis is devoted to the study of azo dyes and their organometallic complexes, which are a particular class of chemistry whose importance and interest to remain our considerable days. The dye industry is nowadays a permanent investigative sector that continues to grow.
The content of this thesis presents a contribution to the study of some coloring substances containing the chromophore azo -N = N- and their organometallic complexes subdivided as follows:
A general introduction, to position the interest of the subject, followed by a first chapter a bibliographic overview of dyes, azo dye compounds and their metal complexes history, generalities, application then we presented the various techniques experimental used.
The second chapter deals with the synthesis of a series of azo dyes followed by an analytical study of characteristic structures obtained by conventional spectroscopic methods: IR, 13C NMR, 1H NMR, UV-Visible, elemental microanalysis and a structural resolution and crystal X-ray diffraction study of new synthesized compounds.
The third chapter is devoted to the synthesis of a series of new organometallic complexes using the new chromogenic azo compounds synthesized as ligands with different metals as: Cu(II), Ni(II), Co(III), followed by an analytical study of characteristic structures obtained by conventional spectroscopic methods: IR, , 1H NMR, UVVisible, elemental microanalysis and a structural resolution and crystal X-ray diffraction study of new synthesized complexes.
The synthesized ligands are usually based on the skeleton of the azobenzene, they are aromatic or pseudo-aromatic systems linked by an azoic group (-N = N-). They are obtained by treating primary aromatic amines with nitrous acid, in a reaction known diazotization followed by diazo-coupling, these azo compounds obtained underwent
complexation reaction with different metals: Cu(II), Ni(II), Co(III) to yield organometallic complexes or metal-dyeing dyes. |
