Abstract
Dimethyldioctadecylammonium (DODA+) was used as a surfactant to react with the high-nuclear transition-metal cluster-containing polyoxometalate K5Na11[Ni9(OH)3(H2O)6(HPO4)2(PW9O34)3]·52H2O (POM-1), resulting in an organic–inorganic hybrid complex (DODA)16[Ni9(OH)3(H2O)6(HPO4)2(PW9O34)3]·36H2O (SEP-1), which exhibits characteristic thermotropic liquid crystalline behavior. Here, the high-nuclear transition-metal cluster-substituted polyoxoanions were firstly introduced into liquid crystalline materials. The chemical composition of the obtained SEP-1 was determined by IR spectra, elemental analysis, and thermogravimetric (TG) analysis. Also, polarized optical microscopy, differential scanning calorimetry (DSC), and variable temperature X-ray diffraction (VT-XRD) were performed on SEP-1 to confirm its thermotropic liquid crystalline behavior.
