| Résumé : |
Two series of new disazo dyes were prepared by diazotising 4,4'-diaminodiphenylsulphonamide and 4,4'-diaminodiphenylurea and coupling with 3-methyl-1-phenyl-pyrazoline-5-one, 2-methylindole, 8-hydroxyquinoline, 2-phenylindole, 1-methyl-2-phenylindole, 3-amino-1-phenyl-pyrazoline-5-one. These dyes were characterised by ultraviolet–visible, Fourier transform infrared, nuclear magnetic resonance spectroscopic techniques and elemental analysis. The spectral characterisation of the dyes was evaluated with respect to visible absorption properties in various solvents. The effects of acid and base on the visible absorption maxima of the dyes were also reported. In addition, the antimicrobial effect of the dyes was evaluated. |
