| titleOfInvention | Isothiocyano fluorine-containing tetrabiphenyl liquid crystal compound, preparation method thereof, liquid crystal composition and application |
| abstract | The invention discloses a fluorine-containing tetrabiphenyl liquid crystal compound of isothiocyanic group, a preparation method thereof, a liquid crystal composition and an application thereof, wherein the structure of the fluorine-containing tetrabiphenyl liquid crystal compound of isothiocyanic group simultaneously has a tetrabiphenyl structure, an alkyl substituent group, an F atom, a-NCS group and other groups, the tetrabiphenyl structure ensures that the liquid crystal compound has the advantage of large optical anisotropy, the alkyl substituent group can reduce the melting point of the liquid crystal compound, so that the liquid crystal compound has the advantage of relatively low melting point, the F atom can increase the dielectric constant of the liquid crystal compound, the-NCS group prolongs the length of a tetrabiphenyl pi-electron conjugated system, the optical anisotropy of the liquid crystal compound can be increased, when the liquid crystal compound is applied to a liquid crystal material with high dielectric anisotropy, the dielectric loss of a liquid crystal microwave device is favorably reduced due to the comprehensive effect of the groups, the phase modulation capability is improved and the quality factor of the liquid crystal material is improved. |
