“…Also, it has been shown that the conformation changes are responsible for the orientation of molecules in the smectic layers, the layer spacing and the mechanical and shock‐sensitive FLC alignment in the cells and displays . Taking into account these requirements and the new approach to preparing anisotropic compounds from 3,6‐disubstituted cyclohex‐2‐enones and other similar intermediates , we synthesized the mesomorphic chiral poly‐ p ‐phenylenes ( I‐V ) with different lateral substituents and investigated the relevant relationships between their properties and the molecular structure. …”
In this paper, we describe the effect of the molecular structure of chiral anisotropic compounds and materials on their mesomorphic and physico chemical properties. Modifications of the molecules via cyclic and bridge fragments or via lateral substituents allowed the preparation and optimization of specific mixtures for different display applications. The formation of defect free layers in ferroelectric liquid crystals stable against various mechanical or temperature deformations was studied. A new electro‐optic effect based on chiral‐nematic mixtures for creating high‐speed devices with switching time less than 1 ms was developed.

“…We propose to use the substituted cyclohexenones, isoxazolines, and similar to them polyfunctional compounds as the key intermediates for the preparation of different types of anisotropic substances and materials. It was found that anisotropic Mannich salts ( 1 ), UV curable substituted vinylketones ( 2 ), various of cyclohexene, phenylcyclohexane, biphenyl, terphenyl, or quaterphenyl derivatives, the LC compounds with negative dielectric anisotropy ( 3‐6 ), which form, as rule, nematic phase at low temperature and in a wide temperature range and are characterized a high value of negative dielectric anisotropy (Δε = −5‐7), can be successfully prepared using this approach.…”
In this article, we show how inorganic and organic structured surfaces, anisotropic materials can be prepared and used for display and photonic applications. The presented results demonstrate that the design of anisotropic materials, the electrochemical formation of structured surfaces, and their combination can provide desirable variations in the anisotropic material properties; in the parameters of structured surfaces for improved satisfaction of the requirements for using them as the components for display and photonic applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
