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[Mo 36(NO) 4O 108(H 2O) 16]·33H 2O 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.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[Mo 36(NO) 4O 108(H 2O) 16]·33H 2O polyoxoanion was prepared.
