“…At high tilt this will lead to the appearance of ripples in the homogeneous structure. This is very similar to the instability appearing in the electroclinic switching in the smectic A* phase, 27,28 where the period in the layer spacing decreases but the effect is the same.…”

The change in the orientational order of ferroelectric liquid crystal molecules during the bending of the plastic cell substrate was studied with a polarizing optical microscope and birefringence data. The optic axis of neighboring striped domains gets widen while optic axis of one striped domain rotates more than that of the adjacent one does as a radius of curvature of the substrate gets shortened. Also the width of each stripe is increased and the liquid crystals in each domain orients more coherently. By the measurements of birefringence for the obliquely incident light, the liquid crystal molecules are found to rotate to the surface normal direction, too.

The Influence of Carbosilane Nanosegregation on the Dynamics in ‘de Vries‐type’ Liquid Crystals

The mesogens QL32-6, QL33-6 and QL-34-6 contain 5-phenylpyrimidine cores and terminal nanosegregating carbosilane end groups of different lengths and are known to exhibit 'de Vries-type' properties of varying strength. We report a systematic study of the influence of the nanosegregating sublayer on the dynamics and rotational viscosities of the collective modes in the smectic A* (SmA*) and smectic C* (SmC*) phase using dielectric spectroscopy. It was found that the dynamics of the Goldstone mode corresponding to phase angle fluctuations are almost not affected while the relaxation time and rotational viscosity of the soft mode are influenced by the degree of nanosegregation. In other words, the nanosegregating sublayer does not influence the dynamics of ferroelectric switching in the SmC* phase, but is critical in inducing 'de Vries-type' properties.
