    摘要： The use of a compound of formula (I) wherein R1 is an alkyl or alkenyl group, either of which may be optionally interposed with one or more oxygen or sulphur atoms, R2 is an alkyl or alkenyl group, Y′ and Y″ are independently selected from oxygen or sulphur, n is an integer from 1 to 5, X is a direct bond or a C1-4alkylene or C2-4alkenylene chain, and A is group comprising one or two rings which are independently selected from aryl, heterocylic or cycloalkyl rings, and when there are two rings, they are bonded together directly or by way of a C1-4alkylene or C2-4alkenylene group, for increasing the u.v. stability of a liquid crystal mixture. The compounds of formula (I) are u.v. stable and are useful in liquid crystal devices which are exposed to high levels of u.v. light such as phosphor display cells.Certain compounds are novel and these form a further aspect of the invention.

    摘要： Anisotropic compounds having negative DC anisotropy and improved photochemical stability have the formula (1) given in patent claim 1; none of the benzene rings present in the molecule (1) is bonded directly to two oxygen atoms, as a result of which quinoidal bonding states which reduce the photochemical stability of anisotropic compounds in the case of benzene rings with two lateral nitrile groups are excluded.
