Problems solved by technology

However, when these compounds are added to a liquid crystal composition for antenna use, there is a problem that Δn is not necessarily sufficient, and Tni is not high enough (Patent Document 1)
In addition, compounds having a tetralin (1,2,3,4-tetrahydronaphthalene) structure have been reported as compounds showing liquid crystal phases (Patent Document 2), but these compounds do not necessarily show sufficiently large Δn, In addition, the dielectric constant anisotropy in the high-frequency region is low, and the phase modulation characteristics are insufficient
Furthermore, as a compound to solve these problems, a compound having an azotolane (azotolane) structure has been reported (Patent Document 3), but there is a problem of low reliability

[0301] [Chemical 54]

[0302]

[0303] Under a nitrogen atmosphere, add 10.0 g of the compound represented by formula (I-1-1), 0.3 g of copper iodide (I), and 0.5 g of bis(triphenylphosphine)palladium dichloride (II) in a reaction vessel , triethylamine 25mL, tetrahydrofuran 50mL. While stirring at room temperature, a solution obtained by dissolving 9.9 g of the compound represented by the formula (I-1-2) in 50 mL of tetrahydrofuran was added dropwise, and stirred at room temperature for 1 hour. 10% hydrochloric acid was poured into the reaction liquid, and extraction was performed with toluene. The organic layer was washed with brine, and purified by column chromatography (silica gel, toluene) and recrystallization (toluene / hexane), thereby obtaining 9.0 g of the compound represented by the formula (I-1-3).

Abstract

The invention provides a compound, a composition, a liquid crystal composition and application thereof. The present invention provides a compound represented by general formula (I), a liquid crystal composition containing the compound, and an element using the liquid crystal composition. The compound of the present invention has a large refractive index anisotropy [Delta] n, sufficiently high Tni, high compatibility with a liquid crystal composition, and a large dielectric constant anisotropy in a high-frequency region. Therefore, the material can be effectively used as a material for elements such as a high-frequency phase shifter, a phased array antenna, an image recognition device, a distance measuring device, a liquid crystal display element, a liquid crystal lens or a birefringent lens for stereoscopic image display. [Formula 1].

Description

technical field [0001] The invention relates to a compound, a liquid crystal composition containing the compound, an element using the liquid crystal composition and applications thereof. Background technique [0002] Liquid crystal compositions are being used for displays such as mobile terminals such as smartphones and tablet devices, televisions (TVs), and window displays. As a novel use of the liquid crystal composition, an antenna for transmitting and receiving radio waves between a mobile body such as a car and a communication satellite has attracted attention. [0003] Traditionally, satellite communications have used parabolic antennas. However, when using a mobile object, the parabolic antenna must always be directed toward the satellite, requiring a large movable part. However, an antenna using a liquid crystal composition can change the direction of transmission and reception of radio waves through the movement of liquid crystals, so the antenna itself does not n...
