Liquid crystals are a state of order between crystals and liquids.
They have imperfect long range orders of orientation and position. Thus, they can be fluid like a liquid and they can have anisotropic properties like crystals. The term 'liquid crystal' covers a wide area of chemical structures, physical properties and technical applications. 4,400 files available in this online-facility are extracted from the LiqCryst Database Ver 2.1 by Volkmar Vill, Institute of Organic Chemistry, University of Hamburg. The Data LiqCryst contains information about structures and properties of all thermotropic liquid crystalline compounds.
