Abstract
Mesogenic compounds of formula I-Z are suitable for use in mesogenic media. Such mesogenic media can exhibit a blue phase and comprise component A, consisting of one or more compounds of formula I-Z, and, optionally a component B, consisting of one or more compounds selected from the group of compounds of formulaeI-M and I-U, wherein the parameters are as defined herein. The media can also be stabilized by a polymer. The media can be used in electro-optical light modulation elements and displays.
