英文摘要: Eight homologous series of fluorinated phenyl 4-[(4-nalkoxyphenyl)ethynyl]benzoates have been synthesized. Textural observations by polarizing microscopy and DSC measurements of the phase transitions show that most of these comounds are thermotropic liquid crystals with nematic and smectic A phases; furthermors, several show monotropic highorder smectic phases. The results showed that the SmA phase is enhanced with increasing degree of fluorosubstitution on the para-and meta-positions of the terminal phenyl groups. The mesomorphic properties of these compounds are also affected jby the drection of ester bonds. The effect of triple bonds is also discussed.
