摘要: Fluorinated 4"-cyano substituted terphenyls of general formula (I), wherein R.sub.1 is selected from alkenyl, H, R, RO and RCO where R is alkyl or perfluoroalkyl containing up to 12 carbon atoms, n is 1, 2 or 3 and the lateral fluorosubstituent(s) may be in any of the available substitution positions are provided. These have liquid crystalline properties and may be used as components of liquid crystal materials.
