Abstract
Four novel azo disperse dyes based on 1-(4-bromobenzyl)-4-phenylpiperazine were synthesized in two steps, using alkylation and azo coupling reactions. Chemical structure of the dyes was characterized and confirmed by the Ultraviolet Visible, Fourrier Transform Infrared, Proton Nuclear Magnetic Resonance and Carbon Nuclear Magnetic Resonance analyses. The solvatochromic behavior of the dyes was studied in a set of 10 solvents with different polarity and considerable results were obtained. The prepared dyes were applied as disperse dyes for dyeing polyester fibers and their dyeing properties were evaluated. The fastness properties of the dyed fabrics such as wash, light and rubbing fastness degrees were measured by standard methods. Investigation of antioxidant activity of compounds was carried out by ferric reducing antioxidant power (FRAP) method. The activity data show that the synthesized dyes B1-B4 have promising antioxidant activity.
