Fast-Switching Low-Temperature Liquid Crystal Mixtures

Abstract

The metastable chiral smectic C phases of the compounds

have been made technically useful by alloying to different two- and three-component systems with enantiotropic behaviour. These systems can serve as a base for multi-component systems of higher order for optimizing various properties.

In a similar way, the inconveniently high-lying ferroelectric phases of the compounds

have been taken down to a useful temperature range. The mixtures have an excellent UV stability and are well adopted for use in high speed bistable SSFLC devices.
