Ferroelectric and antiferroelectric chiral multilactate liquid crystalline materials with negative dielectric anisotropy

Original language description

The correlation between the molecular structure and resulting behaviour for chiral liquid crystalline materials attracts considerable attention of scientific community dealing with self-organizing systems due to their high potential applicability for photonics and optoelectronic devices. In this work the mesomorphic, electro-optic and dielectric properties have been discussed in the light of molecular structure-property correlations on two chiral multilactate liquid crystalline materials. The compounds exhibit negative dielectric anisotropy (Δε) of around -5 in the ferroelectric phase and moderately high values of spontaneous polarization (130 nC/cm2). The temperature dependence of the response time, τ, bulk viscosity, η and the activation energies in the ferroelectric phase have been determined. These results shed important light on the emergence of these materials as a smart alternative for their application in advanced electro-optic and photonic devices.
