Hybrid materials composed of tetraethoxysilane and heteroaryl 4-substituent-2-aminothiazoles were prepared. 4-Substituted acetophenone, thiourea and iodide were used to generate the intermediate, 4-substituted-2-aminothiazole, as coupling component, which was then coupled with p-nitroaniline and p-methoxyaniline to yield heteroaryl 4-substitued thiazole azo dyes. The dyes subsequently underwent hydrolytic polycondensation with vinyltriethoxysilane and tetraethoxysilane to yield hybrid, heteroaryl thiazole azo dyes, whose chemical structure was characterized using FT-IR, 29Si NMR, 1H NMR and EDS.
