以光学活性的4,4,4-三氟-3-苯基丁酸为原料,合成了新型手性液晶掺杂剂。螺旋扭曲力(HTP)的大小在很大程度上受不对称框架和核心部分之间的连接的影响。手性掺杂剂,4,4,4-三氟-1-(4-己氧基苯基)-3-苯基-1-丁酮显示出非常大的HTP值(21.0 m m-1)。
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 ).
