چکیده
The chiral carbosilane-terminated liquid crystal 2-[(2S,3S)-2,3-difluorohexyloxy]-5-[4-(12,12,14,14,16,16-hexamethyl-12,14,16-trisilaheptadecyloxy)phenyl]pyrimidine () undergoes a smectic A*-smectic C* phase transition with a maximum layer contraction of only 0.2%. It exhibits an electroclinic effect (ECE) comparable to that reported for the 'de Vries-like' liquid crystal and shows no appreciable optical stripe defects due to horizontal chevron formation.

Electroclinic effect in a chiral paranematic liquid-crystal layer above the bulk nematic-to-isotropic transition temperature.
Electroclinic measurements are reported for two chiral liquid crystals above their bulk chiral isotropic-nematic phase transition temperatures. It is found that an applied electric field E induces a rotation θ [∝Ε] of the director in the very thin paranematic layers that are induced by the cell's two planar-aligning substrates. The magnitude of the electroclinic coefficient dθ/dE close to the t...
متن کاملSurface electroclinic effect in ferroelectric liquid crystal
Surface electroclinic effect in chiral nematic IN") phase of high-tilt-angle ferroelectric liquid crystal has been studied by dielectric relaxation and electro-optical method in a homogeneously aligned, thin samples in the frequency range of 400 Hz to loo kHz at different temperatures. The electroclinic effect in the N* phase observed in the surface layers is due to the effect of surface anchor...
متن کاملLight-induced director reorientation through the electroclinic effect and optic axis rotation in a chiral smectic A liquid crystal.
We report the observation of light-induced director reorientation under the application of an electric field in a chiral smectic A liquid crystal owing to the temperature dependence of the electroclinic coefficient. We also demonstrate the occurrence of another light-induced phenomenon that leads to optic axis rotation, whose origin is not yet clear. Finally, we show that thermal indexing canno...
متن کاملChiral Periodic Mesoporous Organosilica in a Smectic-A Liquid Crystal: Source of the Electrooptic Response
Chiral periodic mesoporous organosilica (PMO) materials have been shown to deracemize a configurationally achiral, but conformationally racemic liquid crystal in which the PMO is embedded. In particular, application of an electric field E in the liquid crystal’s smectic-A phase results in a rotation of the liquid crystal director by an angle proportional to E, which is detected optically — this...
متن کاملSynchrotron X-ray Microbeam Characterization of Smectic a Liquid Crystals under Electric Field
When an electric field is applied to chiral smectic A (SmA) liquid crystals, a tilt is induced in the director of orthogonal SmA liquid crystals (electroclinic effect). The layer shrinkage due to the tilted smectic arrangement is mitigated by local layer deformation. This paper presents detailed measurements of the local layer spacing under the electroclinic effect of the chiral SmA phase in a ...
