  • Chiral compounds, cholesteric and ferroelectric liquid crystal compositions comprising these chiral compounds, and liquid crystal displays comprising these liquid crystal compositions
    Patent number: 8883037
    Abstract: Chiral liquid crystal compounds of the general formula (1): in which at least one of R1 and R2 is a chiral substituent, K may be a single bond or the same as K1-5 and K1-5 denote a six-membered ring system which rings may be at least partially unsaturated, wherein the number of atoms in these rings or ring systems between the two atoms forming a part of the link to the next ring, or to one of the substituents R1 and R2, does not differ by more than one if counted in the clockwise, and in the counter-clockwise sense, starting from the same atom in each case, X1-20 denote alkyl, or alkoxy, or fluorinated alkyl, or fluorinated alkoxy groups, or atom H, or halogen atoms, mixtures comprising such chiral liquid crystal compounds, and liquid crystal displays comprising such mixtures as active ingredients.
    Type: Grant
    Filed: April 15, 2013
    Date of Patent: November 11, 2014
    Assignee: Tetragon LC Chemie AG
    Inventors: Wolfgang Haase, Artsiom Lapanik
  • CHIRAL COMPOUNDS, CHOLESTERIC AND FERROELECTRIC LIQUID CRYSTAL COMPOSITIONS COMPRISING THESE CHIRAL COMPOUNDS, AND LIQUID CRYSTAL DISPLAYS COMPRISING THESE LIQUID CRYSTAL COMPOSITIONS
