Synthesis and spectral characterization of azo dyes derived from calix[4]arene and their application in dyeing of fibers

In this study, the synthesis and characterization of two new upper rim functionalized azocalix[4]arene dyes have been obtained by coupling calix[4]arene with different diazo compounds of 3,5-dicarboxyaniline and 4-aminobenzene sulphon amide. The characterization of these dyes has been carried out by...

Description
Summary:In this study, the synthesis and characterization of two new upper rim functionalized azocalix[4]arene dyes have been obtained by coupling calix[4]arene with different diazo compounds of 3,5-dicarboxyaniline and 4-aminobenzene sulphon amide. The characterization of these dyes has been carried out by elemental analysis, FT-IR and 1 H NMR spectra. The effect of varying dielectric constants of solvents on the absorption spectra of azocalix[4]arenes ( 1 , 2 , 3 , 4 ) and commercial Isolan Gelb SGL ( T ) have been examined by UV–Vis spectrophotometer. These azocalix[4]arene dyes have also been used for dyeing textile fibers like cotton, wool, acetate, polyester and polyamide fibers. Their dyeing and fastness properties have also been discussed.
