New chiral dopants for nematic liquid crystals were synthesized using optically active 4,4,4-trifluoro-3-phenylbutanoic acid. The magnitude of helical twisting power (HTP) was largely influenced by the linkage between the asymmetric frame and the core moiety. The chiral dopant, 4,4,4-trifluoro-1-(4-hexyloxyphenyl)-3-phenyl-1-butanone showed extremely large HTP value (21.0 m m 1 ).
