Abstract: An aligned film comprises a dried mixture of a lyotropic chromonic liquid crystal material and a dopant selected from the group consisting of dyes having a molecular weight within one order of magnitude of the liquid crystal material and block co-polymers. An example of an aligned film may be transparent to visible light but not transparent to polarized light in the ultraviolet and/or infra-red portions of the electromagnetic spectrum. A method of making an aligned lyotropic chromonic liquid crystal-based film comprises providing a mixture of a lyotropic chromonic liquid crystal material and a dopant in a solvent for the liquid crystal material, applying the mixture to a substrate, and removing the solvent to produce an aligned lyotropic chromonic liquid crystal-based film.

Abstract: A cholesteric display including a liquid crystalline mixture having a dipolar dopant dissolved in the liquid crystalline mixture and the resulting mixture is reflecting light in the visible range of the spectrum when in planar state. In accordance with another aspect, a process includes forming a composition with a dipolar molecule to result in a liquid crystal dipolar dopant, and liquid crystal is added to the composition. In accordance with still another aspect, a device includes a liquid crystal composition includes a cholesteric liquid and a dipolar dopant. The liquid crystal composition is switchable between a focal-conic state and a planar state in the presence of an electric field and is stable in the respective state when the electric field is removed.
