  Synthesis and Characterization of Cholesterol-Based Tetramers

  摘要：

  Novel symmetrical liquid-crystal tetramers were designed and synthesized. The length of the central spacer and the outer spacers has been varied. The molecular structures of the target compounds were confirmed by Fourier transform infrared and proton nuclear magnetic resonance spectroscopy. The thermal phase behavior of the tetramers was investigated by polarizing optical microscopy and differential scanning calorimetry. All of the liquid-crystal tetramers showed either a chiral nematic mesophase or chiral nematic and smectic mesophases.

  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.
