Abstract[English]
The present invention relates to isothiocyanatoethynylbenzene derivatives of formula (I) in which the occurring groups have the meanings defined in claim 1, to liquid crystal media comprising the isothiocyanatoethynylbenzene derivatives, and to high-frequency components comprising these media, especially microwave components for high- frequency devices, such as devices for shifting the phase of microwaves, tunable filters, tunable metamaterial structures, and electronic beam steering antennas (e.g., phased array antennas), and to devices comprising said components. The invention further relates to an optical component comprising said liquid-crystalline media, operable in the infrared region of the electromagnetic spectrum. The invention further relates to the use of said LC medium in the infrared (IR) region and to devices comprising said optical component.[French]
La présente invention concerne des dérivés d'isothiocyanatoéthynylbenzène de formule (I), les groupes présents ayant les significations définies dans la revendication 1, des milieux à cristaux liquides comprenant les dérivés d'isothiocyanatoéthynylbenzène, et des composants à haute fréquence comprenant ces milieux, en particulier des composants micro-ondes pour des dispositifs haute fréquence, tels que des dispositifs pour décaler la phase de micro-ondes, des filtres accordables, des structures de métamatériaux accordables, et des antennes de direction de faisceau électronique (par exemple, des antennes réseau à commande de phase), ainsi que des dispositifs comprenant lesdits composants. L'invention concerne en outre un composant optique comprenant ledit milieu cristallin liquide, utilisable dans la région infrarouge du spectre électromagnétique. L'invention concerne en outre l'utilisation dudit milieu LC dans la région infrarouge (IR) et des dispositifs comprenant ledit composant optique.
