Synthesis and Characterization of Surfactant-encapsulated Polyoxoanions: (CnH2n+1)2N(CH3)212Mo36(NO)4O108(H2O)16(n=12,18)

摘要

By employing electrostatic interaction as driving force, an organic/inorganic composite with positively charged dimethyl dialkyl-chain ammonium surfactants encapsulating negatively charged (NH-4)12[Mo36(NO)4O108(H2O)16] @33H2O polyoxoanion was prepared. The structure of the novel organic/inorganic hybrid particle with hydrophilic core and hydrophobic shell in a defined stoichiometric ratio was confirmed by element analysis,1H NMR and FT-IR spectra. The property of the polyoxoanion was changed due to the encapsulation and it can be dissolved in organic solvent such as chloroform, benzene and toluene, but not dissolved in water.
