  Novel Fluorinated Ferroelectric Organosiloxane Liquid Crystals

  摘要：

  A progress report on the synthesis and characterisation of a series of fluorinated chiral bi-mesogen low molar mass organosiloxane materials is presented. The mesogenic moiety is identical to that in the TSiKN65F mono-mesogen material reported by Naciri et al., which displays a de Vries-type SmA* phase. The parameter varied across the series is the length of the alkyl chain linking the mesogen moiety to the siloxane. The material with 10 carbon atoms in the chains displays a stable smectic phase with ferroelectric response at room temperature, whereas the materials with 6, 7 and 8 carbon atoms tend to crystallize.

• Mesomorphic properties of multi-arm liquid crystals containing glucose and sorbitol as cores

  Six thermotropic cholesteric multi-arm liquid crystals (MALCs) were synthesized with glucose and sorbitol as chiral cores. b0, b1 and b2 were introduced into hydroxy groups of the chiral cores as the mesogenic units in the arm scaffold. The roles played by the chiral cores and the terminal chain length of the mesogenic units to the mesomorphic behavior of the MALCs were studied. b0, b1 and b2 displayed nematic phase. c0, c1, c2, d0, d1 and d2 exhibited cholesteric phases and wide mesogenic regions. The results indicated that the chiral cores played an important effect on inducing the cholesteric phase and an obvious effect on the melting temperature, clear point and mesophase region of the MALCs, The corresponding melting temperature and the clear point of d0, d1 and d2, were lower than those of the c0, c1 and c2. The mesophase regions of the formers were narrower than those of the latters. The terminal chain length of the mesogenic units played an important effect on mesogenic region, too. The mesogenic region increased as the terminal chain length increasing for the MALCs containing the same chiral core. (c) 2009 Elsevier B.V. All rights reserved.
