A new class of mesogenic compounds, the perhydroazulenes, carrying substituents in their para positions (HAZ derivatives), has been synthesized. The newliquidcrystallinematerials display a broad enantiotropic nemantic mesophase slightly above room temperature without any additional smectic phase. Their physical properties reveal that the perhydroazulene moiety can replace the currently often used

Shown is a bimesogenic compound having high solubility in a liquid crystal compound, a liquid crystal composition, a chiral dopant, an additive including an antioxidant or an ultraviolet light absorber, and a polymerizable liquid crystal compound, each of which is used in other bimesogenic compounds or a liquid crystal display device, while maintaining desired physical properties.
A compound is represented by formula (1), a liquid crystal composition contains the compound, conjugate fibers with an encapsulated liquid crystal obtained from the liquid crystal composition, and a liquid crystal display device is obtained from the conjugate fibers with the encapsulated liquid crystal.
