  Microwave-assisted synthesis of novel oligomeric rod-disc hybrids

  摘要：

  Microwave-assisted syntheses of five new oligomeric liquid crystals (LC) are reported for the first time consisting of rufigallol-based core attached to which 8-cyanobiphenyl units via flexible alkyl spacers. The synthesis of the target compounds was challenging since classical reactions failed to produce these hybrids. Chemical structures of these hybrids were determined by H-1 NMR, C-13 NMR, IR, UV spectroscopy and elemental analysis. The thermotropic liquid crystalline properties of these new compounds were investigated by polarizing optical microscopy (POM), differential scanning calorimetry (DSC) and X-ray diffractometry (XRD).
