摘要: The disclosure relates to fluorinated chiral liquid crystals that incorporate a cyclohexyl grouping in their structure. They can be used as dopants and lead to mixtures of ferroelectric liquid crystals that have an application in display systems. They meet the following chemical formula. ##STR1## with 1.ltoreq.n.ltoreq.14 if X=CH.sub.2 Y=--CH.sub.2 -- with R=CmH.sub.2m+1 and 5.ltoreq.m.ltoreq.16 ##STR2##
