摘要：

In the present work discusses synthesis, structural characterization and electrochemical investigation on some azo dyes derived from substituted benzothiazoles. The conventional diazo-coupling method was adopted to afford the heterocyclic azo dyes of benzothiazoles having pyrazole moiety. The obtained azo dyes were characterized by FT-IR, UV-visible, fluorescence, (HNMR)-H-1 and, mass spectrometric techniques. The quantum chemical studies (DFT) was also used to interpret the structural properties of the compounds by using B3LYP program at 6-311++ (d, p) basis set. Further, the cyclic voltammetry was used to study the electrochemical behavior of the synthesized azo dyes in 0.1 M H2SO4 solution on a glassy carbon electrode at different scan rates.
