Abstract
An azo dye derived from sulphanilic acid was synthesized in moderate yield by a coupling reaction between a diazonium salt of the sulphanilic acid and aniline at 0-5 °C. The resulting azo derivative was characterized using nuclear magnetic resonance (NMR) and various spectroscopic methods such as uv-vis, infrared radiation (IR) and ms. The electric conductivity of the resulting 4-(p-aminophenylazo) benzene sulphonic acid was determined and found to be 0.917875 × 10 -7 (·cm) -1 . The 4-(p-aminophenylazo) benzene sulphonic acid showed a semiconducting behavior at 295 K without the need of adding a doping agent. The electric conductivity measurements revealed that the synthesized 4-(p-aminophenylazo) benzene sulphonic acid possesses an electric resistivity ρ of 1.089472779 10 7 ·cm which renders this azo dye a semiconducting material.
