Cyclohexylbiphenyls, their preparation and use in dielectrics and electrooptical display elements |
摘要 |
Compounds of the formula <IMAGE> wherein R1 is alkyl of 1-12 C atoms and R2 is an optionally perfluorinated alkyl, alkoxy or alkanoyloxy group, each of 1-12 C atoms are valuable liquid crystalline components for broadening the mesophase temperature range of liquid crystalline dielectrics having negative dielectric anisotropy.
