Title (EN) PHENYLDIOXANES
(FR) PHENYLDIOXANNES
Abstract:
(EN) Phenyldioxanes of formula (I), wherein R1 is an alkyl or alkenyl residue each with up to 16 C atoms, wherein one or two non-adjacent CH2 groups of these residues may be replaced by -O-, -S-, -CO-O- or -O-CO-, Q1 and Q2 are each independently (a), (b) or (c), (a) is (d) or (e); L1 and L2 are each independently F or H; and Y is Cl, F, CN, CF3, OCF3 or OCF2H; m and n is 0 or 1, are suitable as components of liquid crystal media.
(FR) Des phényldioxannes répondent à la formule (I), dans laquelle R1 est un résidu d'alkyle ou d'alkényle dont chacun possède jusqu'à 16 atomes de carbone, et dans laquelle un ou deux groupes CH2 non contigus de ces résidus peuvent être remplacés par -O-, -S-, -CO-O-, ou -O-CO-; Q1 et Q2 sont indépendamment l'un de l'autre, (a), (b) ou (c); (a) est (d) ou (e); L1 et L2 sont, indépendamment l'un de l'autre, F ou H; et Y est Cl, F, CN, CF3, OCF3 ou OCF2H; m et n sont 0 ou 1; ces composés sont aptes à servir de constituants de milieux à cristaux liquides.
