Abstract

Compounds containing at least one C—C triple bond of the formula IR-[A-Z]-AA-[Z-A]-[Z-A]-R  I,which have neutral dielectric anisotropy, 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 giga- and terahertz region, comprising these media. The liquid-crystalline media serve, for example, for the phase shifting of microwaves for tuneable phased-array antennae.
