摘要： Optically active, mesogenic 1,3-dioxolane-4-carboxylates are suitable as dopes in liquid-crystal mixtures. They result in liquid-crystalline ferroelectric phases having short switching times and in electroclinic phases having large electroclinic coefficients. Their particular advantage is that they induce a helix of very large pitch, meaning that helix compensation by further dopes is unnecessary. In addition, the 1,3-dioxolane-4-carboxylates exhibit high UV stability.

摘要： The use of optically active tetrahydrofuran-2-carboxylic acid esters as dopants in liquid-crystal mixtures, liquid-crystal mixtures containing same and novel optically active tetrahydrofuran-2-carboxylic acid esters.Optically active tetrahydrofuran-2-carboxylic acid esters containing a mesogenic molecular building unit are suitable as dopants in liquid-crystal mixtures. They result in liquid-crystalline ferroelectric phases having short switching times and in electroclinic phases having large electroclinic coefficients. A further advantage is that they induce a helix having a very small pitch so that they are also suitable for helix compensation in LC mixtures.The compounds are symbolized by the general formula: ##STR1## in which the symbols and indices essentially denote: R.sup.1 =alkyl/alkenyl or tetrahydrofurancarbonyloxy or -thio; j, l, n=zero, 1 or 2; k, m=zero or 1; --A.sup.1, --A.sup.2, --A.sup.3 =phenylene, cycloalkylene or corresponding heterocyclates containing nitrogen, oxygen or sulfur; --M.sup.1, --M.sup.2 =bridges such as --CO--O, --OCH.sub.2 or --CH.dbd.CH; X=oxygen or sulfur.

摘要： A process for producing a liquid-crystal cell which comprises the steps of:(a) providing a curable sealant portion in the periphey of the side of an electrode plate that has an electrode or electrodes;(b) (i) coating a ferroelectric liquid-crystal composition on the portion surrounded by said sealant portion, with a spacer being preliminarily provided in said portion;(ii) coating spacer-containing ferroelectric liquid-crystal composition on the portion surrounded by said sealant portion; or(iii) coating a ferroelectric liquid-crystal composition on the portion surrounded by said sealant portion and thereafter providing a spacer over said composition;(c) defoaming the coated layer of the liquid-crystal composition by heating during or after evacuation;(d) placing the other electrode plate in such a way that the side of said other electrode plate which has an electrode or electrodes faces the side of said one electrode plate containing the thermally defoamed coated layer of the liquid-crystal composition and compressing the two electrode plates together; and(e) curing said sealant.
