Abstract
The preparation and properties of liquid crystal compounds having an achiral core and chiral tail units composed of the 1-cyanoalkoyl grouping (chiral cyanohydrin ethers) are described. The newly made compounds are shown to be useful as components of ferroelectric liquid crystal mixtures which exhibit high speed, multistate electro-optic switching properties making them ideally suited to certain electro-optic display device applications.
