Abstract
The optical, electrical and thermal properties of unsymmetrical imine with two fluorinated chains are described. The structure of imine was characterized by means of 1H, 13C NMR spectroscopy and elemental analyses and the results show an agreement with the proposed structure. The wide-angle X-ray diffraction [WAXD(T)] technique in different temperatures was used to probe the structural properties of the azomethine. Mesomorphic behaviour was investigated via differential scanning calorimetry (DSC) and polarizing optical microscopy (POM) studies. Additionally, the mesomorphic behaviour of the azomethine presented in this work was compared with other azomethines. The absorption (UV-vis), photoluminescence (PL) and thermoluminescence (TL) features of the compound are documented. The sample was irradiated with a test dose of 2 Gy Co-60 gamma rays. Current–voltage (I–V) measurements were performed on an ITO/Az/Al device in the dark and during irradiation with light (under illumination of 1000 W/m 2).
