Description

<p>Systematic studies were undertaken in the selected liquid crystalline Schiff bases showing well-ordered smectic B (SmB) phase in order to check the changes of reorganization of molecules in phase transitions observed. Using complementary experimental methods helps in understanding how the Iso - SmA, Iso - SmB, SmA - SmB and SmB - SmE transitions influence structural properties and molecular dynamics. In particular the infrared (FT-IR) and dielectric (DS) spectra, results of differential scanning calorimetry (DSC), polarized microscope textures (POM) and X-ray diffraction patterns (XRD) of 5BBAA were studied as a function of temperature. The obtained data are discussed in relation to molecular dynamic s and structure of each phase.</p>
