Azo dyes are the most important class of dyes accounting for more than 50 % of all commercial dyes or colourants. They have found many applications in various fields of science and technology [1,2]. The importance behind this study is to synthesize azo dyes containing heterocyclic rings due to their superior properties. The introduction of heterocyclic ring as coupling components have made possible the synthesis of good colourants with chromophoric strength and brilliant colours. Such dyes have high level dyeing properties and excellent fastness properties [3]. The usability of heterocyclic azo dye lies in the field of textiles, papers, leather, additives, food stuff, cosmetics, holographic data storage materials, xerography laser materials, laser printing, materials for organic solar cells and chemosensors, etc. [4-9]. Heterocyclic azodyes are found to be useful in second harmonic nonlinear optical material and optical switching devices [10-12]. The strong bathochromic effect of heterocyclic system is due to its diene character [13]. Towns [14] has reported the developments in azo dyes derived from heterocyclic azo components.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
