More Information
Summary:The invention discloses a 1,1'-binaphthalene-2,2'-diol chiral compound, a preparation method and application thereof. The 1,1'-binaphthalene-2,2'-diol chiral compound is shown as a formula I and has a high HTP (High Thread Pitch) value, it means that a liquid crystal mixture with high-spiral warping, namely fine pitch, can be prepared by only adding a small quantity of the chiral compound shown as the formula I in a liquid crystal mixture. The addition of small quantity of the chiral compound shown as the formula hardly causes adverse effects on parameters of dielectric anisotropy (Delta epsilon), optical anisotropy (Delta n), a clearing point (Cp) and a viscosity (Gamma 1) of the liquid crystal mixture; and compared with the existing chiral compound, the 1,1'-binaphthalene-2,2'-diol chiral compound has the effect of reducing response time including rise time (Tau on) and fall time (Tau off).
