Abstract

Waugh- and Silverton-type polyoxometalates (POMs) K₃(NH₄)₃[MnMo₉O₃₂] and H₈[CeMo₁₂O₄₂] are enwrapped by dioctadecyldimethylammonium (DODA⁺) forming the surfactant- encapsulated POMs (SEPs) (DODA)₆[MnMo₉O₃₂]·16H₂O (DODA-MnMo₉) and (DODA)₈[CeMo₁₂O₄₂]·9H₂O (DODA-CeMo₁₂), which exhibit typical thermotropic liquid-crystalline properties. Here, the Waugh- and Silverton-type polyoxoanions centered by metal cation were firstly introduced into liquid crystal materials. The chemical composition of these SEP complexes was determined by IR spectra, elemental analysis and TG analysis. Also, the polarized optical microscopy, differential scanning calorimetry (DSC), variable temperature X-ray diffraction (VT-XRD) and transmission electron microscopes (TEM) were performed to characterize their liquid-crystalline behavior.
