COMPOUNDS HAVING A C-C TRIPLE BOND AND USE THEREOF IN LIQUID-CRYSTAL MIXTURES

The present invention relates to compounds containing at least one C-C triple bond of the formula I R1-[A1-Z1]m-A2A3-[Z2-A4]n-[Z3-A5]o-R2 I, which have neutral dielectric anisotropy, to the use thereof for high-frequency components, to liquid-crystalline media comprising the compounds, and to high-...

Beschreibung
Zusammenfassung:	The present invention relates to compounds containing at least one C-C triple bond of the formula I R1-[A1-Z1]m-A2A3-[Z2-A4]n-[Z3-A5]o-R2 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.
