摘要

Chiral 2,4,5-tri-substituted 1,3-dioxane compounds (I), with different substituents containing a mesogenic group, and their diastereomers are new. Chiral 2,4,5-tri-substituted 1,3-dioxane compounds of formula (I), with different substituents containing a mesogenic group, and their diastereomers are new: [Image] R1>[P-Y1>-(A1>)m-Y2>-]qM-Y3>-(A2>)n-Y4>- group; R2>, R3>[P-Y1>-(A1>)m-Y2>-]qM-Y3>-(A2>)n-Y4>'-; A1>, A2>spacers with 1-30 carbon atoms; M : a mesogenic group; Y1>, Y2>, Y3>, Y4>a single bond, -O-, -S-, -CO-, -CO-O-, -O-CO-, -CO-N(R)-, -(R)N-CO-, -O-CO-O-, -O-CO-N(R)-, -(R)N-CO-O- or -(R)N-CO-N(R)-; Y4>' : -O-, -O-CO-, -O-CO-O- or -O-CO-N(R)-, with the O atom attaching R2>, R3> to the 1,3-dioxane ring; R : hydrogen or 1-4C alkyl; P : H, 1-12C alkyl, a polymerizable group or a group containing a polymerizable group; m, n : 0 or 1; q : 1, 2 or 3. Independent claims are also included for: (a) liquid crystal (LC) compositions containing chiral compound(s) (I); (b) polymerizable LC compositions containing chiral compound(s) (I); (c) optical devices produced using these compositions; (d) printed or coated substrates, dispersions and emulsions, films or pigments prepared using the polymerizable LC compositions.
