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 studi
ed by thermal polarizing microscopy. The relationship between the prop
erties and chemical structures of all these target compounds, especial
ly the influence of flexible oxymethylene linkage in core on the forma
tion of mesophases, is also discussed in detail.
