Decidedly higher clearing temperatures and often also broader mesophases are exhibited by axially fluorinated cyclohexane derivatives 1 and 2 relative to their nonfluorinated analogues. A convenient method for the multigram synthesis of 1 and 2 , which represent a promising new type of liquid crystals with positive or negative dielectric anisotropy, is presented.
