Influence of Achiral So Host on the Values of Spontaneous Polarization and Rotational Viscosity of Ferroelectric Mixtures

Abstract Spontaneous polarization and rotational viscosity of Sc guest host mixtures was measured. Three different hosts were compared.

Synthesis and Mesomorphic Properties of 1,2-(4-Substituted Phenyl) Ethynes Containing Fluoro Atoms

Abstract Its important to evaluate an influence of different structural units on the mesomorphic and physical properties of mesogenic compounds. A number of 1,2-dipheny Iethynes containing fluorine atom in an aromatic ring (I, II) and several fluorine atoms in a terminal alkyl chain (II, III) were obtained in this work.

Mesomorphic Properties of New 5-Alkyl-2-Pyrimidinols Esters

Abstract A synthesis of a number of 5-alkyl-2-pyrimidinol esters was conducted, their mesomorphic properties were examined. Two ring esters of said pyrimidinols are nonmesomorphic, while three ring esters are typical mesogens, forming nematic either nematic-smectic mesophases.
