Abstract:
The present invention relates to 1,4-diethynylbenzene derivatives having substituents in the 2,3-position (cf. formula I, Claims), to the use thereof for high-frequency components, to liquid-crystalline media comprising the compounds, and to high-frequency components, in particular antennae, especially for the gigahertz range, comprising these media. The liquid-crystalline media serve, for example, for the phase shifting of microwaves for tuneable ‘phased-array’ antennae.
