Due to their vivid colors, azo dyes are among the most popular synthetic dyes in the fashion industry and are also used in cosmetics, paints and food colorings.  Original synthesis of aromatic azo dyes involves using an azo coupling reaction, but now greener methods using reagents on a polymer support resin have been developed.  The goal of this project was to study if this new greener method using polymer-supported reagents could be used to synthesize novel bis-azo compounds using 1,8-diaminonapthalene, 1,5-diaminonapthalene and 2,6-diaminopyridine as the analine derivative.  Data representing the successfully synthesized bis-azo compounds using this method will be presented along with their characterization using UV-Vis, IR and 1H-NMR.
