Abstract

Abstract Four series of tolane-based chiral liquid crystals that incorporate a tetrafluorophenyl moiety and a flexible oxymethylene linkage into the core have been synthesized. The mesomorphic properties have been studied by thermal polarizing microscopy. The relationship between the properties and chemical structures of all these target compounds, especially the influence of flexible oxymethylene linkage in core on the formation of mesophases, is also discussed in detail.
