We investigated the effect of optical purity on the temperature range of coexistence phenomenon of the phase transition from SmC* to SmC*A for various enantiomeric mixtures. The results obtained using dielectric and electro-optic techniques show that

In this work, a theoretical model is developed, to investigate in more detail the electric field-temperature phase diagram ( E–T ) of antiferroelectric liquid crystals. The analysis shows that it is possible to obtain a complete description of the

Some chiral series with benzoate cores (CnHH, CnF3 and CnF2) are reported. These series (hydrogenous, monofluoro-substituted in positions 2 and 3 of the first phenyl ring near the chiral chain) display very rich polymorphism, including SmC*, SmC*α,

Some of the antiferroelectric liquid crystal compounds (C12HH, C12F3 and MHPOBC) displaying ferrielectric phase are investigated. In a planar sample the ferrielectric (SmC*FI1) existing between the ferroelectric (SmC*) and the anticlinic (SmC*A) phas

Optical Rotatory Power measurements have been done on different chiral tilted smectics which lead to reproducible results. The high-temperature uniaxial SmA and SmC\(\) phases do not show any ORP due to the lack of in-plane anisotropy at the mesoscop

We have experimentally investigated the unwinding process of the ferroelectric Sm- C * phase of a chiral AFLC smectic liquid crystal compound 12OF1M7 using the electro-optic properties, microscopic observations and constant current method. We found t

The temperature variations of the order parameter invariants are measured in the uniaxial and biaxial nematic phases of different mixtures of potassium laurate, 1-decanol, D 2 O. They show that the unixial to biaxial nematic phase transitions are sec
