5,6,7,8 tetrahydro-2-naphthylamine based novel azo dye: Synthesis, spectral characterizations, DFT and latent fingerprinting application studies
Abstract
The present study describes about the synthesis, spectral characterization and computational studies of a new series of azo dyes produced from 5,6,7,8-tetrahydro-2-naphthylamine (3a-3d).The aforementioned compounds are generated through the conventional method of diazotization of 5,6,7,8-tetrahydro-2-naphthylamine, followed by coupling reactions with four different coupling components, such as α-naphthol, β-naphthol, 6-bromo naphthol, and 8-hydroxy quinoline under suitable experimental conditions.The resulting azo dyes are spectroscopically characterized and confirmed using UV, FTIR, NMR, and Mass spectral methods. The salvotochromic and fluorescence studies are performed by using various solvents CHCl3, DMF, DMSO and Ethanol.A latent fingerprint application for the selected azo dye (3c) was also carried out, as it shows highest emission intensity in fluorescence studies. Additionally, computational DFT studies on the synthesized azo dyes are carried out in order to gain greater comprehension of the molecular properties which offer information regarding the compound's nonlinear optical (NLO) properties and its application.
