Described herein are heterocyclic liquid crystal compositions that can allow for the adjustment of their refractive indices by the application of an electric field, such as those described by the following formula (1) wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , X, Y are as described herein. In addition, selectively dimmable reverse-mode polymer dispersed liquid crystal (PDLC) 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. |
