The properties of ferroelectric compound (S)-(+)-4-(1-methylheptyloxycarbonyl)phenyl 4′-(4-cyanoacetoxybut-1-oxy) biphenyl-4-carboxylate and its ability of an antiferroelectric phase induction in mixtures

From the discovery of the partially bilayer smectic A phase to blue phases in polar liquid crystals

“…Here the presence of branched alkyl chain and chirality is necessary. [188,189,190] Two types of the induced antiferroelectric SmC Ã A phases are known. The first one is observed when two or more chiral synclinic compounds (ferroelectric) are mixed together and the first component is low polar (both terminal substituents are alkane type with -Oor COO groups inserted within them) and the second component has non-chiral alkyl chain terminated with a CN group.…”
