Description

We synthesized a new optically active carboxylic acid with a trifluoromethyl asymmetric frame and a biphenyl structure, 4,4,4-trifluoro-3-{4-(4-methoxyphenyl)phenyl}butanoic acid(5*). New chiral dopants for nematic liquid crystals were derived from 5*, and their helical twisting power (HTP) values were measured. Their HTP values were largely influenced by the linkage between the asymmetric frame and the core moiety. The chiral dopant, 4,4,4-trifluoro-1-(4-hexyloxyphenyl)-3-{4-(4-methoxyphenyl)phenyl}-1-butanone (8*)showed the largest HTP value.
