摘要： A range of eutectic mixtures containing at least three compounds having the formula ##SPC1##Where X.sup.1 is an alkyl group, an alkoxy group or a substituted phenyl group ##SPC2##Where R is an alkyl or alkoxy group, are described. The eutectic mixtures extend the temperature ranges over which their constituent compounds exhibit liquid crystal properties and are thus useful in liquid crystal devices operating in those temperature ranges.

摘要： A novel liquid crystal material contains a compound having a molecular structure such that the material exhibits a liquid crystal phase, the molecular structure of the compound being ##SPC1##Or an orthosubstituted derivative thereof, where X and Y are different parasubstituents of the kind which promote liquid crystal behaviour, where the para substituent is a group selected from the following list; an alkyl group, an acyloxy group, an unsaturated group or an alkoxy group having more than one carbon atom; and where the para-substituent Y is a group selected from the following list; a cyano group, a nitro group, a group which includes a terminal cyano group, a group which includes a terminal nitro group and an acyloxy group. The material may be the said compound or it may be a multi-component solution or mixture containing it. The liquid crystal material may be nematic, smectic or cholesteric depending on the selection of the substituents X and Y. A device such as a twisted nematic effect device, incorporating the material may be operated at low temperatures. The material does not suffer from significant chemical and/or photochemical decomposition when used in a liquid crystal device.
