Ferroelectric Liquid Crystals Having Various Cores. Effect of Core Structure on Physical Properties

Article abstract of DOI:10.1246/bcsj.66.568

Ferroelectric liquid crystals (FLC's) having various cores were synthesized and the effect of the different core structures on the spontaneous polarization (P_s) values was investigated.The results indicate that the core structure has a great influence on the P_s value and introduction of a heterocycles such as pyrimidine and thiadiazole ring in the core increases the P_s value.Moreover, several compounds in this series are interesting as chiral dopants for FLC, because the mixtures containing them showed superior properties as FLC mixture.
