ON THE COEXISTENCE OF SmC* AND SmCA* PHASES IN BINARY CHIRAL-DOPANT ANTIFERROELECTRIC MIXTURES
نویسندگان
چکیده
We present the results from investigations on a series of binary chiraldopant liquid-crystalline mixtures. The racemic host materials possess tilted smectic phases with varying strengths of synclinic and anticlinic ordering (SmC and SmCalt phases respectively). The dopants used were either a strongly synclinic-favouring non liquid-crystalline chiral material (commonly used in FLC chiral-dopant mixtures) or a strongly anticlinic (antiferroelectric) material ((S)-MHPOBC). The electrooptic and dielectric properties of the mixtures were investigated in test cells of different thickness and the influence of each mixture component on the observed physical properties is discussed.

Rotational bias of an antiferroelectric liquid crystal studied by polarized Fourier transform infrared spectroscopy
Experimental studies of the absorbance vs polarization angle of the incident ir beam on a cell have been carried out for several absorbance bands in the SmA phase and in electrically induced ferroelectric states F(1) and F(2) of the SmCA* and SmC* phases of an antiferroelectric liquid crystal. The various absorbance profiles are quantitatively analyzed in terms of the rotational bias parameters...
متن کاملEffect of cell surfaces on the stability of chiral smectic-C phases.
The effect of surfaces on the stability of smectic-C* (SmC*) variant phases is investigated. The results obtained using dielectric spectroscopy by varying the cell thickness show that the temperature ranges of SmCalpha*, SmCA*(1/2) , and SmCA*(1/3) phases decrease with decreasing cell thickness, and the SmCA*(1/3) phase is more stable than the SmCA*(1/2) phase. The relative stability of any pha...
متن کاملCharacterization of Interlayer Orientational Structures in Liquid Crystal Phases Using Resonant X-Ray Scattering
Introduction: Resonant x-ray scattering has proven to be a unique method for measuring nm orientational periodicities in liquid crystal compounds. In particular, the interlayer orientational periodicities that occur in smectic-C* (SmC*) liquid crystal phases can only be observed when scattering at the resonance-edge of one of the atoms in the core of the liquid crystal molecule. Our resonant me...
متن کاملAdvanced glycation end products impair the functions of saphenous vein but not thoracic artery smooth muscle cells through RAGE/MAPK signalling pathway in diabetes
Saphenous vein (SV) and internal thoracic artery (ITA) are commonly used bypass conduits. However, graft failure occurs in SV rather than in ITA, especially in diabetes (DM). The mechanism for this difference has not been fully understood. Accumulation of advanced glycation end products (AGEs) and activation of AGEs receptor (RAGE) could accelerate smooth muscle cells (SMC) proliferation in DM,...
متن کاملVascular composition, apoptosis, and expression of angiogenic factors in the corpus luteum during prostaglandin F2alpha-induced regression in sheep.
Corpora lutea and blood samples were collected from superovulated ewes 0, 4, 8, 12 and 24 h after prostaglandin F(2alpha) (PGF) analog injection on day 10 of the estrous cycle. Changes in vascular cell and fibroblast composition, apoptosis and mRNA expression for several angiogenic factors in the corpus luteum (CL) were determined. While peripheral progesterone concentration decreased at 24 h a...
