Abstarct: Triazoles are important class of compounds in drug discovery and material science. In this work new derivatives of 1,2,3-triazoles lixnked to dye were prepared by click reaction. azo dye of N-methyl-N-[4-(4-nitrophenylazo)phenyl]benzene amine was synthesized by the reaction of diazotized aromatic amine (para nitroaniline) and then reacted with reaction product of N-methylaniline and propargyl tosylate. 2-nitrophenyl azide, benzyl azide, 4-chloro-3-nitrophenyl azide, 3-nitrophenyl azide, 4-nitrophenyl azide, 4-chloro-2-nitrophenyl azide, 2-chloro-4-nitrophenyl azide, was reacted with N-methyl-N-[4-(4-nitrophenylazo)phenyl]propargyl amine wich was prepared insitu by the reaction of N-methylaniline with propargyl tosylate, then CuAAC reaction to synthesize new 1,2,3-triazoles products lixnked to the dye. All synthesized compounds were characterized by FT-IR, 1H-NMR and 13C-NMR analysis
