  The disclosed subject matter provides a chiral host-guest composition for a ferroelectric liquid crystal mixture, the host-guest composition comprising a chiral guest compound and an achiral host compound, wherein the host-guest composition induces a greater degree of polarization in the liquid crystal mixture than is induced in the mixture with a comparable amount of the chiral guest compound in the absence of the achiral host compound. The chiral guest is a fluorinated compound comprising a aryl or heteroaryl core substituted with an alkyl chain, wherein the alkyl chain includes one or more fluorine atoms, each fluorine atom being bonded to a chiral carbon atom. The achiral host possesses a central thiadiazole core, with at least one aryl/heteroaryl wing, further substituted with alkyl or alkoxy groups.
