Abstract
Described herein are liquid crystal compositions containing a five-member heterocyclic ring that can allow for the adjustment of their refractive indices under the application of an electric field. In addition, selectively dimmable reverse-mode polymer dispersed liquid crystal elements and devices using the aforementioned compositions are also described, which are transparent when no voltage is applied and opaque when a voltage is applied.
