Sažetak
Aromatic and heteroaromatic azo compounds represent the most numerous and diverse group of synthetic dyes, used not only as textile dyes, but also in many other different industry fields: for dyeing various substrates, biological-medical research, in the field of nonlinear optics and optical data storage. Aromatic diazo components, in the synthesis of azo dyes, are increasingly being replaced by heteroaromatic diazo components because the prepared heterocyclic azo dyes show better dyeing properties such as color tone and brightness, and better light fastness compared to the corresponding carbocyclic azo dyes. In this work, an efficient method for the synthesis of a small library of 6-azo-substituted benzothiazole molecules by diazotization reactions of three 6- amino-substituted benzothiazole derivatives and by copulation of the corresponding diazonium salts to two N, N-disubstituted aniline derivatives have been presented. The obtained dyes have been tested as disperse dyes for polyester (PES) and polyamide (PA) textile material. All six tested dyes have good application properties for dyeing PA textile materials, while dyes 4-6 proved to be good for PES. In order to determinate biological activity of presented new azo dyes in vitro antiproliferative and antibacterial evaluations of dyes 1-6 were performed and the results have been presented.
