Synthesis of new ferroelectric liquid crystals and their novel ferroelectricity
Abstract
A new type of ferroelectric liquid crystal, the 4′-alkoxybiphenyl-4-yl (2S,3S)-3-methyl-2-halogenopentanoates, has been synthesized; these compounds possess novel ferroelectricity, with spontaneous polarization and dielectric constant larger than 10–7 C/cm2 and 6000, respectively.
