AbstractLiquid crystal(LC) materials with 1,3,2-dioxaborinane group have been synthesized and their physical properties have been investigated to get new LC mixtures. The test LC samples were made up of a base LC material doped with 5, 10, 15, 20, and 25% of each compound in weight. We have measured optical and dielectric anisotropy, nematic-isotropic phase transition temperature, and threshold voltages as a function of doping concentration. From our measurements, it is found that each compound has different properties compared with other ones. So, these results would contribute to development of new LC mixtures for LCD applications.

AbstractA set of new, blended nematic liquid crystal mixtures to improve the performance of highly multiplexed TN-displays are presented. The physical and electro-optical properties of new LC mixtures have been investigated, along with the frequency and temperature dependence of threshold voltage about newly developed liquid crystals. The multiplexable mixtures are completely miscible and can be blended, thus leading to new mixtures covering a wide range of threshold voltages 1.2 > V10> 2.0 V, nematic-isotropic phase transition temperatures 60 > Tc > 100[ddot]C, and/or optical anisotropies 0.13>Δ n>0.18.
