چکیده

Smectic blue phases ( BP(Sm)) are thermotropic liquid crystalline phases which exhibit both three-dimensional orientational order, such as classical blue phases, and smectic positional order. BP(Sm) appear as the three-dimensional counterpart of twist grain boundary phases. X-ray scattering and optical polarizing microscopy provide information on the hexagonal and cubic symmetries of these new phases.

Structural Measurements in Blue Phases with Smectic Ordering

A new phase sequence: twist grain boundary SA to blue phases without cholesteric phase inbetween has been recently observed in a chiral compound. We have performed X-ray studies on this compound to analyze the smectic ordering through the phase

Optical activity measurements in the smectic blue phases

Optical activity measurements have been performed on the smectic blue phases (BPSm), which are a new kind of chiral liquid crystal. BPSm exhibit both three-dimensional orientational order, like the classical blue phases, and smectic positional order. Thus, they can be viewed as the three-dimensional counterpart of the twist grain boundary phases. A comparison with the optical activity of the cl...

Generation of frustrated liquid crystal phases by mixing an achiral nematic-smectic-C mesogen with an antiferroelectric chiral smectic liquid crystal.

By mixing the achiral liquid crystal HOAB, exhibiting a nematic (N)-smectic-C (SmC) mesophase sequence, with the chiral antiferroelectric liquid crystal (AFLC) (S,S)-M7BBM7, forming the antiferroelectric SmC(a)(*) phase, at least seven different mesophases have been induced which neither component forms on its own: a twist-grain-boundary (TGB(*)) phase, two or three blue phases, the untilted Sm...

Reentrant nematic and smectic A phases : the dielectric approach

2014 We report the first dielectric investigations of the double reentrant phenomenon N-SA-N-SA. These measurements are in good agreement with an earlier X-Ray analysis. Both smectic A phases present very different behaviours in their dielectric constants as well as in their parallel relaxation times. In addition, the reentrant nematic can be seen as the simultaneous presence of two types of sm...
