    摘要: A liquid crystal medium having an optically isotropic liquid crystal phase is described, which has stability to heat, light and so on, a broad temperature range of liquid crystal phase, a large optical anisotropy and a large dielectric anisotropy. A liquid crystal composition is described, which includes an achiral component T and a chiral dopant and exhibits an optically isotropic liquid crystal phase. The achiral component T contains, as its first component, at least one compound selected from compounds represented by formula (1),

    摘要: The purpose of the present invention is to achieve a composition for forming a low dielectric constant resin which is suitable for use in a substrate for radar, next-generation communication devices and the like using higher frequencies, while having high heat dissipation properties. The present invention enables the achievement of a polymerizable composition, which is able to be molded by a solution process, while exhibiting thermal conductivity and low dielectric properties lower than those of conventional liquid crystal polymers, by curing a polymerizable polycyclic compound that has less conjugates or polar groups, while exhibiting higher linearity or symmetry of each molecule.
