Structural studies of the bond-orientational order and hexatic-smectic transition in liquid crystals of various compositions
I. A. Zaluzhnyy, R. P. Kurta, E. A. Sulyanova +9
We report on X-ray studies of freely suspended hexatic films of three different liquid crystal compounds. By applying angular X-ray cross-correlation analysis (XCCA) to the measure…
Linkage-length dependent structuring behaviour of bent-core molecules in helical nanostructures
Hanim Kim, Anna Zep, Seong Ho Ryu +6
We studied the correlation between the molecular structure and the formation of helical nanofilaments (HNFs) of bent-core dimeric molecules with varying linkage lengths. To obtain…
Switching mechanism in polar columnar mesophases made of bent-core molecules
Ewa Gorecka, Natasa Vaupotic, Damian Pociecha +2
The behavior of polar columnar phases made of bent shaped molecules (B_1Rev and B_1RevTilted) was studied under applied electric field. There are two competing mechanisms of switch…
General phase diagram for antiferroelectric liquid crystals in dependence on enantiomeric excess
E. Gorecka, D. Pociecha, M. Cepic +2
The phase diagram of the prototype antiferroelectric liquid crystal MHPOBC in dependence of enantiomeric excess was measured. It was shown that the SmCbeta phase in very pure sampl…
