“…25 Spectroscopic grade solvents (Merk) were used throughout the experiment. Stock solutions of the dyes (1 × 10 3 M) were prepared in methanol and its concentration in the experimental condition was maintained at 5 × 10 5 M. Absorption spectra were recorded on Shimadzu-160 UV-Visible spectrophotometer at 300 K with sensitivity ± 0.1 nm.…”

The influence of solvent polarity on the absorption spectra of some synthesized azo dye with heterocyclic moieties and -naphthol (1-3) have been investigated using a UV-Visible spectrophotometer. The spectral characteristics of the azo dyes (1-3) in different solvents at room temperature were analyzed. The solvatochromic empirical variables like  * , , and  have been used to discuss the solvatochromic behaviour of the dyes and to evaluate their contributions to the solute-solvent interactions. A multi-parameter regression model for quantitative assessment of the solute/solvent interaction and the absorption has been used to explain the solvent effect on azo dyes (1-3).

Azo disperse dyes Ia-f -Va-f were synthesized from corresponding amines, where IR and visible spectra were evaluated. The prepared dyes were used for dyeing polyester, polyester woolen type and wool fibres. A range of bright and leveled shade have been obtained on application of these disperse dyes. The K/S values for various dyed substrate are in the following order, Wool > polyester/wool > polyester.

“…Several papers have been published on the use of these compounds as antimicrobial [3], antifungal [4], anti-inflammatory activity [5], anesthetic [6] and antiviral drugs [7]. 2-A minothiazoles and their derivatives are also used in the syntheses of various types of dyes [8][9][10][11]. In continuation of our previous studies [9,[12][13][14][15] on the synthesis of a variety of thiazole derivatives fro m the readily obtainable cheapest starting materials for dyeing polyester fabrics, we focused on the synthesis of several new S/N heterocyclic azo dyes and their applications as azo-disperse dyes for dyeing polyester fibers.…”

A series of 5-arylazo-2-(arylidenehydrazino)-2-th iazo lin -4-one dyes 3 and 4 was prepared by cyclocondensation of hydrazonoyl bro mides 2 with various thiosemicarbazone derivatives 1. While the synthesis of 3-amino-N-(5-aryla zo-2-thiazo lyl)-thieno[2,3-b]pyrid ine-2-carbo xamide dyes 8 was achieved by the reaction of 2-(N-chloroacetyl)-5-ary lazo -thiazo le derivatives 5 with 4,6-dimethyl-2-mercaptonicotinonitrile fo llowed by heterocyclizat ion of the obtained sulfide derivatives 7 in a solution of ethanol containing sodium etho xide. These dyes were applied as disperse dyes for dyeing polyester fibers and their characteristics and fastness properties have been measured. The dyed fibers exh ibit very good to excellent washing, perspiration and sublimat ion fastness properties, with little variation in good to excellent rubbing and light fastness.
