G. Tang et al., Synthesis and mesomorphic properties of 4-[(4-n-polyfluoroalkoxy-2,3,5,6-tetrafluorophenyl)ethynyl]phenyl fluoro-substituted benzoates, LIQ CRYST, 28(11), 2001, pp. 1623-1626
A series of 4-[(4-n-polyfluoroalkoxy-2,3,5,6-tetrafluorophenyl)ethynyl]phen
yl fluoro-substituted benzoate liquid crystals have been synthesized. Their
phase transition temperatures have been measured by optical polarizing mic
roscopy and confirmed by DSC. The results show that a highly fluorinated te
rminal chain impairs mesomorphic properties.
