Use of 4-fluoropyrimidine derivatives as component for ferroelectric liquid crystal mixtures

摘要

The use of a fluoropyrimidine derivative of the general formula (I) as component in a ferroelectric liquid crystal mixture comprising 2 to 20 components, <IMAGE> (I) in which the symbols have the following meaning: R1 and R2 independently of one another are, for example, straight-chain or branched alkyl having 1 to 16 carbon atoms, a and b are, for example, both equal to 0 or 1, <IMAGE> <IMAGE> for example, phenylene or cyclohexylene, and -M1- is, for example, -CO-O-, -O-CO-, -CH2-O- or -O-CH2, leads to improved switching characteristics in electrooptical display devices.
