Abstract
Three series of fluorinated bistolane-type liquid crystals have been synthe sized. Their mesomorphic properties were studied by optical polarizing micr oscopy and DSC. These compounds exhibit only a broad nematic phase with hig h clearing points, wide phase transition temperatures and low melting point s. The effects of lateral fluoro-substitution and the introduction of the t etrafluorophenylene moiety are discussed in detail.
