Light tuning of selective Bragg diffraction of the oblique helicoidal cholesteric
Igor Gvozdovskyy, Halyna Bogatyryova, Natalia Kasian +2
It is known that the oblique helicoidal cholesteric structure (Ch), which is formed in alternating electrical field applied to the chiral nematic phase (N*) at temperatures…
Bragg diffraction of higher orders on oblique helicoidal liquid crystal structures
H. Bogatyryova, V. Chornous, L. Lisetski +1
For the oblique helicoidal structure of the chiral twist-bend nematic-forming mixture of CB7CB/CB6OCB/5CB doped by light-sensitive chiral compound based on azo-fragment, two conseq…
Oblique helicoidal state of the twist-bend nematic doped by chiral azo-compound
Vitalii Chornous, Alina Grozav, Myhaylo Vovk +4
A novel light-sensitive chiral dopant ChD-3816 (an azo compound containing 4-hexanoyloxyphenyl and 2-isopropyl-5-methylcyclohexylbenzoate moieties) was used for inducing helical tw…
Light-controllable hybrid aligning layer based on LIPSS on sapphire surface and PVCN-F film
I. Gvozdovskyy, D. Bratova, Z. Kazantseva +4
The creation of aligning layers for the uniform orientation of liquid crystals is significant for both research and the application of liquid crystals. For all applications, the cr…
Chiral ferronematic liquid crystals: a physico-chemical analysis of phase transitions and induced helical twisting
K. G. Nazarenko, N. A. Kasian, S. S. Minenko +4
A possibility was assessed to modify physico-chemical properties of ferronematic mixtures by introducing additional mesogenic and non-mesogenic components. The mixture, consisting…
Light-controllable chiral dopant based on azo-fragment: synthesis and characterization
V. Chornous, V. Bratenko, M. Vovk +6
We present the newly synthesized chiral dopant 2-[(2-isopropyl-5-methylcyclohexyl)oxy]-2-oxoethyl 4-{(E)-[4-(decyloxy)phenyl]diazenyl}benzoate (ChD-3501), consisting of azo- and al…
Twist-bend nematics and heliconical cholesterics: a physico-chemical analysis of phase transitions and related specific properties
Natalia Kasian, Longin Lisetski, Igor Gvozdovskyy
Certain nematic liquid crystals, e.g., those formed by banana-shaped molecules, can exhibit a low-temperature twist-bend nematic (Ntb) phase. Upon addition of chiral dopants, a chi…
Nonlinear laser lithography as a new technology for the high-quality alignment of nematic liquid crystals
Ihor Pavlov, Andrey Rybak, Andrii Dobrovolskiy +5
It is well known that today two main and well studied methods for alignment of liquid crystals has been used, namely: rubbing and photoalignment technologies, that lead to the chan…
The alignment of nematic liquid crystal by the Ti layer processed by nonlinear laser lithography
I. Pavlov, A. Rybak, A. Dobrovolskiy +5
It is well known that the alignment of liquid crystals can be realized by rubbing or photoalignment technologies. Recently nonlinear laser lithography was introduced as a fast, rel…
