Abstract
Quantum-chemical calculations using the Density Functional Theory (DFT) approach for structural analysis of new azodye sodium(E)-2-hydroxy-5-((4-sulfonatophenyl)diazenyl) (trans isomer) is carried out using B3LYP methods with 6-31G∗ basis set. The comparison of measured UV–Vis data, IR and NMR spectra of the molecule with the experimental data were also described which allowed assignment of major spectral features of title molecule. The optimized geometrical parameters obtained by B3LYP methods show a good agreement with experimental data.On the basis of polyvinyl alcohol (PVA) and the dichroic synthesized dye polarizer absorbing in the UV region of the spectrum (λmax=353nm) with the effect of polarization in the absorption maximum 96% was developed. The spectral-polarization parameters of stretched PVA-films were calculated.
