Abstract
A series of novel 1, 4,-Di-Azophenyl-(1/-phenyl-3/-Aryl-4/-Substituted phenyl)-pyrazoles (4a-m) were synthesized by coupling reaction of 1-phenyl-3-(2/-hydroxy phenyl)-4-substituted phenyl-pyrazoles (3a-m) with diazotized 1,4-Diamino phenyl (2). These dyes have been prepared in good yield and were characterized by UV-Visible, FT-IR and 1H-NMR Spectroscopic techniques. The effect of solvent polarity and various PH on dyes in the visible absorption spectra were evaluated.
