Novel compounds for use in liquid gorystal compositions

摘要

The present invention provides a compound of the following general formula (I) and a liquid crystal adjuster containing the compound.;Wherein R ¹ is, for example, a straight or branched chain alkyl radical having 1 to 22 carbon atoms, wherein one -CH ₂ -group may be replaced by -O- or -CO-O- ; Group- (A ¹ ) _a (-M ¹ ) (-A ² ) _b (-M ² ) (-A ³ ) _c (M ³ )-is a group;Is one of. The compounds of the present invention are useful as components of smectic liquid crystal compositions or ferroelectric liquid crystal compositions having a wide temperature range in the Smectic C phase, particularly in the low temperature region.
