Název v původním jazyce

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

Popis výsledku v původním jazyce

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.
