چکیده انگلیسی
In this paper, we reported the three novel heterocyclic azo dyes prepared by the diazotization method using 2-amino-6-ethoxybenzothiazole with three different coupling compounds under suitable optimized experimental conditions. Structural features of the title compounds have been accomplished by the various analytical techniques like UV-Visible absorption spectra, FT-IR, NMR (1H and 13C), elemental analysis and mass spectrometry. Also, solvatochromism of the prepared azo dyes was studied at different solvents with increasing polarity. Further, the electrochemical properties of the synthesized compounds were investigated by using cyclic voltammetric technique. The effects of sulphuric acid and scan rate are also studied at glassy carbon electrode. The overall reaction is diffusion controlled and tentative electrode reaction mechanism was proposed.
