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.
本发明涉及含有至少一个C—C三键的化合物,其化学式为IR1-[A1-Z1]m-A2A3-[Z2-A4]n-[Z3-A5]o-R2I,具有中性介电各向异性,用于高频元件,包括含有这些化合物的液晶介质,以及高频元件,特别是用于千兆赫和太赫兹区域的天线。液晶介质可用于微波相移调制,用于可调相阵列天线。
