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.
