Synthesis and Electrochemical Characteristics of Dyes Based upon 1H-3-Phenyl-6-Methyl-7-Aril-Azo-Pyrazolo[5,1-c>[1,2,4>Triazole

Abstract:

The azoic dyes based upon 1H3-phenyl-6-methyl-7-arilazopyrazolo<5,1-c><1,2,4>triazole were obtained by the coupling of 1H-3-phenyl-6-methylpyrazolo<5,1-c><1,2,4>triazole with various aromatic diazonium salts in alcoholic-alkaline media. The newly synthesized compounds were further investigated by IR spectroscopy, 1H-NMR, 13C-NMR and cyclic voltammetry respectively. While the spectrophotometric methods deliver results indicating that the desired compounds were formed, the electrochemical approach shows the influence of the various substituents over the electronic structure of the molecule. Keywords: azoic dyes, cyclic voltammetry, 1H-3-phenyl-6-methylpyrazolo<5,1-c><1,2,4>triazole, 1H-3-phenyl-6-methyl-7-arilazopyrazolo<5,1-c><1,2,4>triazoles
