| Abstract | A no. of red to violet thienyl-2-azo and thienyl-5-azo disperse dyes were prepd. using Gewald's methodol. Structural characterization of these dyes was carried out using IR, NMR, and mass spectroscopies. UV-visible studies of the dyes in a no. of polar solvents showed a considerable difference in the λmax. The introduction of various substituents to these azo dyes as well as the solvent polarity resulted in absorption in the visible region ranging from 461 to 555 nm. [on SciFinder(R)] |
