A Kind of Liquid crystal intermediate

Post  sherryfu on Thu May 06, 2010 4:16 am

trans, trans-4-(3, 4-Difluorophenyl)-4'-vinylbicyclohexyl with cas number of 142400-92-8 is used as Liquid crystal intermediate. Liquid crystals (LCs) are a state of matter that has properties between those of a conventional liquid and those of a solid crystal. For instance, an LC may flow like a liquid, but its molecules may be oriented in a crystal-like way. There are many different types of LC phases, which can be distinguished by their different optical properties. When viewed under a microscope using a polarized light source, different liquid crystal phases will appear to have distinct textures. The contrasting areas in the textures correspond to domains where the LC molecules are oriented in different directions. Within a domain, however, the molecules are well ordered. LC materials may not always be in an LC phase.
