摘要： A fluorinated compound having a formula:
wherein:


R, is hydrogen or alkyl having up to 12 carbon atoms;
R 2 is selected from hydrogen, alkyl having up to 12 carbon atoms, alkoxy having up to 12 carbon atoms,
wherein R 3 is hydrogen or alkyl having up to 12 carbon atoms, and wherein R 4 is hydrogen, alkyl having up to 12 carbon atoms or alkoxy having up to 12 carbon atoms;
represents a cyclohexane ring which is in the trans configuration if 1,4-disubstituted;
represents a benzene ring; each of X, Y and Zindependently represents hydrogen or fluorine in one or more of the lateral benzene ring positions, provided that at least one of X, Y and Z is present representing fluorine; n = 0 or 1 provided that when
is
and R, is alkyl; with the proviso that in Formula l when n is 1 and
where R is n-alkyl and R 2 is n-alkyl or n-alkoxy the total number of carbon number of carbon plus oxygen atoms in the two groups R 1 and R 2 is less than 10.
