The Preparation, Characterization and the Study of the Linear Optical Properties of a New Azo

Abstract

Azo dye was prepared from 4,4-diaminodiphenyl sulfone with chromotrpic acid by fox method. Azo dye was identified via IR-Infrared spectrophotometer, UV-visible spectroscopy and elemental analysis (CHN). The basic optical properties of azo dye have been studied at room temperature. The optical energy gap was estimated from the absorption coefficient values using Taue’s procedure. The values of the static refractive index , the static dielectric constant , oscillator energy , dispersion energy , the moments of optical dispersion spectra, and the band gap energy have been determined by the Wimple-Didomenico method .
