Photochromic properties of the N-Salicylideneaniline in Polyvinyl Butyral matrix: Experimental and theoretical investigations [pdf]Paper  abstract   bibtex   
a b s t r a c t In the present work, isomerization, photophysical properties, thermal conductivity (l) and spectral study of the N-Salicylideneaniline: 2-[(E)-(phenylimino)methyl]phenol (SA) under the action of UV radiation in the Polyvinyl Butyral (PVB) matrix were studied using the Indicator method and Density Functional Theory (DFT). The electronic absorption spectra of SA and its isomers (SA 1 and SA 2) in dimethylforma-mide (DMF) solutions were also calculated. The nature of absorption bands of SA, SA 1 and SA 2 in the visible and near ultraviolet spectral regions was interpreted. The excitation energies, electronic transi-tions and oscillator strengths for SA, SA 1 and SA 2 have also been calculated. Thermal Conductivity of PVB-films containing SA before and after UV radiation was also measured. A Photochromic PVB -film on the basis of SA for application in optical devices and display technologies was made.
