Synthesis, characterization and photostability study of triazole derivatives

heterocyclic derivative contain triazole ring was synthesized and characterized the product and their structures by infrared spectroscopy, 1H-NMR, 13C-NMR and instrumental techniques. Compound (4) was synthesized by reacting of Schiff base (3) with an three moles of alkyl halide (p-phenyl phenacyl bromide). Final product played an important role in photostabilizer of polymer (PS), and showed the activity as a photostabilizer when exposed to UV light (300 hours).
