文摘A new heteropoly supermolecular compound was synthesized and characterized by elemental analysis, IR and TG-DSC. Six vibrational bands of organic groups were observed in IR spectra and the characteristic bands of heteropoly anion are shifted to a higher frequency as the result of electronic delocalization in the heteropoly anion. The liquid crystal behavior of heteropoly supermolecular compound in organic solvent was firstly studied. When the observation was carried out under the polarimicroscope, the liquid crystal was showed as the smectic phase, which is characterized by heterothermal as well as wide angle XRD.
