Abstract

Liquid crystal materials that exhibit bookshelf structures are provided. When these bookshelf materials are incorporated into a bistable host material, the mixture exhibits a higher switching angle and increased A to C phase transition than bistable hosts without the bookshelf material. These bookshelf materials and bistable compositions are useful in liquid crystal displays, for example.
