Mesomorphic, morphologic and thermotropic properties of 4-hexyl-N-(4-hexadecyloxysalicylidene)aniline

The mesomorphic, morphologic and thermotropic properties of the liquid crystalline material 4-hexyl-N-(4-hexadecyloxysalicylidene)aniline (1) have been investigated. Investigations on the peculiarities of heterophase regions during phase transitions between smectic C mesophase and isotropic liquid have been carried out. Hysteresis in the temperature width of the heterophase regions, temperatures of the phase transitions between smectic C and isotropic liquid, and smectic C and solid crystal and also the hysteresis in the temperature width of the smectic C mesophase in the salicylaldimine compound 1 have been found.
