Description
Technical Field
The present invention relates to a liquid crystal compound and a composition comprising the same, and more particularly, to a novel difluorovinylether-containing liquid crystal compound and a liquid crystal composition comprising the same.
Background
Physically, substances are classified into three states, namely solid, liquid and gaseous. In nature, most materials exhibit only three states of solid, Liquid and gas depending on temperature, and Liquid Crystal (Liquid Crystal) is a new state of matter different from the ordinary solid, Liquid and gas states, and is a state of matter having both Liquid and Crystal properties in a certain temperature range, also called a Liquid Crystal phase or an intermediate phase, and is also called a fourth state of matter.
Liquid crystals are in many kinds, and naturally occurring and artificially synthesized liquid crystals are in many thousands, but they are basically organic compounds. Liquid crystals are classified into thermotropic liquid crystals, lyotropic liquid crystals, induced liquid crystals and flow-induced liquid crystals, according to the conditions under which the liquid crystal phase is formed.
At present, liquid crystal materials used for display are basically thermotropic liquid crystals. Thermotropic liquid crystals are classified into Smectic (semiconducting) liquid crystals (also called lamellar liquid crystals), Nematic (Nematic) liquid crystals (also called filamentous liquid crystals), and cholesteric (cholesteric) liquid crystals (also called helical liquid crystals) depending on the molecular arrangement order state. The physical properties of these phases are known. The molecular structural features of compounds used in the field of electro-optics are generally a rigid backbone comprising, for example, linked 1, 4-phenylene or 1, 4-cyclohexylene groups or heterocyclic ring systems, which are substituted at positions as far apart from one another as possible by so-called mesogenic groups, such as alkyl, alkoxy or cyano groups.
Liquid-crystalline media used in the electro-optical field consist of mixtures of these compounds, and compounds which do not have a interconversion from the crystalline phase to the liquid-crystalline phase are also used. Liquid crystal mixtures are classified into a dynamic scattering type (DS type), a guest-host type (GH type), a twisted nematic type (TN type), a super twisted nematic type (STN type), a thin film transistor type (TFT type), a ferroelectric type (FLC type), and the like. Liquid crystal materials have been widely used for producing liquid crystal display elements such as electronic computers, various measuring instruments, instrument panels for automobiles, electronic notebooks, cellular phones, computers, and televisions.
Hitherto, liquid crystal materials used therefor have been synthesized into various compounds, and they are suitable for use in accordance with the display mode or driving mode and the use thereof. On the other hand, the demand for improving the performance of liquid crystal display elements has been increasing year by year, and in order to meet this demand, development of novel liquid crystal compounds has been continued.
