  New Nematics with High Birefringence

  摘要：

  We prepared new compounds with the hexendiyne unit as central bridging group. The substances are nematic, with clearing temperatures much higher than those of other two ring compounds. They show the highest birefringence ever observed in liquid crystals, modest viscosities and medium dielectric anisotropy. Their stability in low polar mixtures allows their use in displays.
