| titleOfInvention | Optically active cyanobiphenyl compound |
| abstract | NEW MATERIAL:A compound expressed by the formula [n is 3W5: R is -(CH 2 ) a - CH 3 or formula II (a and b are 3W12); * indicates asymmetric carbon]. n EXAMPLE: 4-(6"-Chloro-4"-methylhexyloxy)-4'-cyanobiphenyl. n USE: A liquid crystal display element substance having a low crystal-liquid crystal phase transition point and a high liquid crystal-isotropic liquid phase transition point in providing a cholesteric phase. n PREPARATION: For example, 4-hydroxy-4'-cyanobiphenyl is subjected to etherification reaction with a halide or citrate of an optically active alcohol in the presence of an alkaline compound to afford the aimed compound expressed by the formula. n COPYRIGHT: (C)1988,JPO&Japio |
