Liquid crystals, compounds and mixtures with positive dielectric anisotropies are reviewed. The mesogenic properties and physical chemical properties (viscosity, birefringence, refractive indices, dielectric anisotropy and elastic constants) of compounds being cyano, fluoro, isothiocyanato derivatives of biphenyl, terphenyl, quaterphenyl, tolane, phenyl tolane, phenyl ethynyl tolane, and biphenyl tolane are compared. The question of how to obtain liquid crystal with a broad range of nematic phases is discussed in detail. Influence of lateral substituent of different kinds of mesogenic and physicochemical properties is presented (demonstrated). Examples of mixtures with birefringence ∆n in the range of 0.2-0.5 are given.

“…Several high birefringence molecular structures, such as diphenyldiacetylene [4,5], bistolane [6,7], naphthalene tolanes [8], and thiophenyl-diacetylene [9][10][11] have been studied. Recently some of biphenyl-tolane compounds were synthesized and their properties were investigated [12][13][14].…”

We have designed, synthesized, and evaluated the physical properties of some high birefringence (Dn) isothiocyanato biphenyl-tolane liquid crystals. These compounds exhibit Dn $ 0.48-0.52 at room temperature and wavelength k ¼ 633 nm. Laterally substituted short alkyl chains and fluorine atom eliminate smectic phase and lower the melting temperature. The moderate melting temperature and very high clearing temperature make those compounds attractive for eutectic mixture formulation. A eutectic mixture based on those compounds was formulated and its physical properties evaluated.
