This work includes synthesis of the novel azo compound, which consists of diazotization of 3-nitroaniline followed by reaction with 4-hydroxybenzaldehyde in presence of sodium carbonate. The synthesized azo compound was confirmed by characterization, using FT-IR,1HNMR, 13CNMR and GC-MS spectra. The azo compound was screened for solvatochromism, Halochromism using UV-Vis spectrophotometer, and found that the azo compound exhibited low solvatochromic and good Halochromic properties. While the dying study (Dye-doped Polymer Films), Poly ethylene was found the best polymer dyed by azo compound and showed good absorbance in the UV region. All fabrics were dyed with a yellow color except the cotton exhibiting a light brown color.
