Thiophene-Based Azo Dyes and Their Applications in Dyes Chemistry
نویسنده
چکیده
The thiophene-based azo dyes class of azo dyes have generated considerable interest since its discovery 62 years ago. These dyes have come to be applied to a very large number and variety of fibres and have therefore achieved an importance which is probably greater than the weights used would suggest. The connection between dyeing and fastness properties on the one hand and chemical constitution on the other is in general indefinite. Also, some factors affecting the current application of these dye types are discussed.

Naphthalene-based azo dyes: Synthesis, characterization and dyeing performance on polyester fibers
In the present study, five naphthalene-based azo dyes were obtained using classical azo coupling reactions. The structure of the dyes was characterized and confirmed by the UV-vis, FT-IR, 1H NMR and 13C NMR analyses. The solvatochromic behavior of the dyes was studied in a set of 10 solvents with different polarity and considerable results were obtained. The dyes were applied as disperse dyes t...

In the present study, nine bis-azo dyes based on 5-arylidene-2,4-thiazolidinone were obtained in two steps, using Knoevenagel condensation and azo coupling reactions. The structure of the dyes was confirmed on the basis of spectral data. Analysis of spectroscopic data shows that there is equilibrium between the azo and hydrazone tautomers for all dyes in solutions. Investigation of antioxidant ...

Kaolin-SO3H nanoparticles were prepared via reaction of kaolin and chlorosulfonic acid and characterized by FT-IR, XRD, FESEM, TEM, XRF, EDS, BET and TGA. The activity of this green catalyst was probed by the synthesis of aryl diazonium salts as the starting reactant and then, their diazo coupling with 2-naphthol to form azo dyes in a solvent-free medium at room temperature...
