The present article is a study of the ferroelectric behavior in low-molar-mass organosiloxane liquid-crystal materials classed. A few novel compounds with large tilt angle and wide temperature range of the SmC* phase have been synthesized, and the mesophases exhibited by them have been compared. The mesophases under discussion were investigated by means of polarizing microscopy, differential scanning calorimetry, X-ray diffraction, as well as electro-optical experiments. The influence of the molecular structure on the occurrence of the SmC* phase was investigated. Finally, the electro-optical properties of the SmC* phase, such as tilt angle, dielectric permittivity, and switching behavior, were also measured. As a consequence, the correlation between their electro-optical properties and chemical structures of these compounds is investigated. Copyright Taylor & Francis Group, LLC.
