PREPARATION AND STUDY OF THE ELECTRICAL AND OPTICAL PROPERTIES OF A NEW AZO DYE (4-ACETAMINOPHENOL - (2-(4-AZO))-4- AMINO DIPHEYL SULFONE)

Abstract

Azo dye has received great attention due to its environmental stability, ease of preparation, and its optical and electrical properties. Much work has been carried out on the molecular design, synthesis, and assembly of structures with desired properties [1-3]. Knowledge of optical constants of a material such as refractive index and extinction coefficient are quite essential to examine material’s potential opto-electronic applications [4]. Further, the optical properties may also be closely related to the material’s atomic structure, electronic band structure and electrical properties. In this paper, the dielectric constant  and dielectric loss    have been measured for a new azo dye powder (4-Acetaminophenol–[2-(4-Azo)]-4-Amino dipheyl sulfone) in the frequency range (100 210 ) Hz . The optical constants of the azo dye powder discs of 1cm diameter are determined by optical characterization method, also, the nonlinear optical properties for the azo dye in the ethanol solution were investigated by the use of the Z-scan technique.
