  Symmetrical dimer liquid crystals derived from benzoxazoles

  摘要：

  A series of dimeric twin liquid crystals derived from symmetric heterocyclic benzoxazoles 1a-1f exhibiting single smectic C phase are reported. All benzoxazoles were prepared by condensation of 2-aminophenols with benzaldehydes and then followed by subsequent intramolecular cyclization. The mesomorphic properties were investigated by DSC and POM, and the structure of the mesophases was confirmed as smectic C phases by powder XRD. The formation of mesophases was attributed to the weak dipole force induced by donor-acceptor interaction (D-A). A monolayer conformation was proposed based on the powder XRD data. A value of aspect ratio d/l=0.80-0.92 was calculated from d-spacings and the molecular lengths. By contrast, the odd-even effects by a value of entropy changes Delta S-SmC -> I/R=2.00-6.50 showing odd-even effect for the transition of SmC -> I phases were also associated in twin system.
