Abstract

The synthesis of our targeted phenolic azo dye 6 was initiated by diazotization of 4-aminoacetophenone (1) and diazocoupled with resorcinol (3) to furnish the corresponding the product, 4-(acetylphenylazo)-resorcinol (4). Condensation of 4 with thiosemicarbazide afforded the corresponding thiosemicarbazone 5, which underwent Hantzsch type reaction upon reaction with 4-chlorophenacyl chloride to yield the corresponding thiazolyl-phenylazo-resorcinol dye 6. Polymeric matrix of poly vinyl alcohol was doped with minor concentration of the synthesized dye and their effects on the physical properties was studied including structural and optical properties .
