Abstract
A use of zwitterionic compound in preparation of dynamic-scattering-mode-based liquid crystal material. A liquid crystal material is also described. Such material contains liquid crystal and dopant, and the dopant is zwitterionic compound. A liquid crystal electro-optical device comprising such liquid crystal compound and the use of such optical device are also described. Zwitterionic compound is used as dopant to induce a stable dynamic scattering mode in liquid crystals.
Claims6
A liquid crystal material, comprising:
- a host liquid crystal, wherein the host liquid crystal demonstrates negative dielectric anisotropy;
- and
- a zwitterion dopant, wherein the zwitterion dopant is at least one selected from the group consisting of phenol red, 2,6-diphenyl-4-(2,4,6-triphenyl-1-pyridinio), 5-amino-2-naphthalenesulfonic acid, and 3-(triphenyl phosphorus) propane-1-sulfonate.
