Synthesis and Mesomorphic Properties of Ferroelectric Liquid Crystals Bearing Trans 4-Alkoxycyclohexylpyrimidines

Abstract A homologous series of chiral trans-4-alkoxycyclohexylpyrimidines were synthesized and their mesomorphic properties were evaluated with a DSC and a polarizing microscope. It was found that the presence of a trans-1, 4-disubstituted cyclohexane ring strongly promoted the formation of the SB phase and seems to suppress the formation of the chiral smectic C (Sc*) phase.
