Abstract
New 1,2,4-triazole-based azo-azomethine dyes were synthesized via condensation of 3,5-diamino-1,2,4-triazole with azo-coupled o -vanillin precursors. The effect of time on color intensity and electronic absorption spectra of the dyes were studied. ► In this study four new 1,2,4-triazole-based azo-azomethine dyes have synthesized. ► The tautomerism equilibrium between azo and hydrazone forms in DMSO/EtOH solution was studied. ► The TG results indicate that the dyes are thermally stable. Four new 1,2,4-triazole-based azo-azomethine dyes were synthesized via condensation of 3,5-diamino-1,2,4-triazole with azo-coupled o -vanillin precursors. The prepared dyes were characterized by IR, UV–vis and 1 H NMR spectroscopic methods as well as elemental analyses. Thermal properties of the prepared dyes were examined by thermogravimetric analysis. Results indicated that the framework of the dyes was stable up to 225 °C. Also, the influence of various factors including time and mixed DMSO/EtOH solution on UV–vis spectra of the dyes were investigated.
