Title:
OPTICALLY ACTIVE TRIFLUOROLACTIC ACID DERIVATIVE AND LIQUID CRYSTAL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/1992/020641
Kind Code:
A1
Abstract:
An optically active compound derived from a novel trifluorolactic acid, useful as a component of a ferroelectric liquid crystal composition, and a liquid crystal composition. A compound represented by general formula (I), wherein R?1� represents C�1? to C�18? alkyl, alkoxy, C�2? to C�18? alkanoyl, alkanoyloxy or alkoxycarbonyl; R?2� represents optionally alkoxy-substituted alkyl (where the total number of the carbon atoms is 1 to 15); A, B and C represent each independently the group (a) or (b); v and w represent each independently -COO-, -OCO-, -CH�2?O-, -OCH�2?-, -CH�2?-CH�2?-, -CH=CH-, -C=C- or a single bond; and x and y together represent any of the following combinations: -OCH�2?- and -O-; -OCH�2?- and -OCO-; -OCH�2?- and -OCOO-; -OCO- and -O-; -OCO- and -OCO-; -OCO- and -OCOO-; -COO- and -COO-; -COO- and -CO-; -COO- and -CH�2?O-; -COO- and -CH�2?OCO-; -COO- and -CH�2?OCOO-; -COOCH�2?- and -O-; -COOCH�2?- and -OCO-; -COOCH�2?- and -OCOO-; -O- and -CH�2?O-; -O- and -CH�2?OCO-; and -O- and -CH�2?OCOO-.
