摘要： A liquid-crystal medium having a component A which is one or more compounds of the formula IA and corresponding, novel mesogenic compounds and the preparation thereof. These liquid-crystal media, are used in components for high-frequency technology, and to components of this type which contain the media. The components are suitable, in particular, for phase shifters in the microwave and millimeter wave region, for microwave and millimeter wave array antennae and very particularly for so-called tunable “reflectarrays”.
