“…Such a type of temperature hysteresis has been observed earlier in salicylaldimines [4,27,28], metallomesogens [29], polymer liquid crystals [30][31][32], and in usual liquid crystals [33][34][35][36] for mesophase-isotropic liquid phase transitions and are typical for first-order transitions.…”

The synthesis and investigations of the mesomorphic, thermotropic, thermo-morphologic, and thermo-optical properties of two new salicylaldimine compounds, synthesized by our group, are reported in this work. Temperature transformations of specific textures of the smectic C mesophase, taking place in these compounds, and thermo-morphologic and thermotropic properties of the biphasic regions for direct and reverse phase transitions have been investigated. Temperature hysteresis and enlargement of the biphasic regions have been found. The character of texture transformations and temperature behavior of the optical birefringence indicate to the first order a smectic C-isotropic liquid-phase transition in these salicylaldimine compounds.

Comparative investigations of the thermo-optical, thermotropic, and thermo-morphologic properties of aligned and non-aligned textures in the nematic mesophase over a large temperature interval and in regions of direct and reverse phase transitions between the nematic mesophase and the isotropic liquid have been carried out. The character of the optical transmission and adsorption coefficient has been compared with that of the texture transformations. Nonlinearity of the thermo-optical and thermotropic behavior at the nematic mesophase-isotropic liquid and isotropic liquid-nematic mesophase phase transitions has been observed. Differences in the temperatures of phase transitions for the aligned and non-aligned textures of the nematic liquid crystals have been found.
