Synthesis, characterization, density function theory and NLO investigations of new azo dye

Le résumé fourni par la source

By mixing the dizonium salt of p-amino benzoic acid with acetylacetone, azo dye is synthesized. The FTIR, mass, 1HNMR, and 13CNMR spectroscopies were used to describe the finished product. The density function theory (DFT) via B3LYP and 6-311+G (d,p) high theoretical basis sets is used to improve the shapes of the benzoic acid dye that has already been made better. The nonlinear optical (NLO) resource and its value of a new benzoic acid dye azo are investigated. This is made by computing a few quantum chemistry factors using DFT. We use a laser beam with continuous wave (CW) Gaussian shape output of wavelength 473 through Z-scan to look into the NLO properties by making diffraction patterns (DPs). The first step gives a nonlinear refractive index (NLRI), n2, that is as high as 8×10-7 cm2/W is obtained. To study the all-optical switching, 473 and 532 nm laser beams are used.
