Synthesis of novel siloxane room temperature liquid crystalline

This article's goal was to analyze the synthesis of room temperature liquid crystal materials with low molar mass organosiloxane. The structures contain 4'-hydroxybiphenyl-4-yl 4-hydroxybenzoate core and chiral butyl 2-hydroxypropanoate unit, and organosiloxane on the end of the achiral molecules. A few novel series of room temperature compounds were synthesized, and the mesophases exhibited by them were compared. The mesophases under discussion were investigated using polarizing microscopy, differential scanning calorimetry, and X-ray diffraction. The substituent had a strong influence in reducing the clearing temperatures and increasing temperature range. The influence of the molecular structure on the occurrence of the SmC* phase was investigated in the article.
