Effect of molecular structure on dielectric and electro-optic properties of chiral liquid crystals based on lactic acid derivatives

Popis výsledku v původním jazyce

Self-assembling behaviour of several lactic acid derivatives with several ester linkage groups in the molecular core has been studied. Depending on the molecular structure compounds exhibit the chiral nematic N* phase, the paraelectric orthogonal smectic A* phase and the ferroelectric tilted smectic C* phase being thermally stable over relatively broad temperature range. The temperature behaviour of the spontaneous polarization clearly confirms the second order nature of the SmA*-SmC* phase transition and the first order nature of the N*-SmC* phase transition. The effect of temperature and molecular configuration on the polarization (WP) and on the dispersion (WD) anchoring energy coefficients have been established. The obtained results are discussed in order to contribute the structure – property relationship for the specific class of soft materials which can be used for design of smart multifunctional LC mixtures aimed for optoelectronic and photonic applications.
