Abstract: A series charge transfer salts, ［NMPH］₄GeMo_12-nW_nO₄₀·CH₃CN (n=0, 9, 11, 12), were synthesized from H₄GeMo_12-nW_nO₄₀·mH₂O and N-methylprolinedone, and they were crystallized out from CH₃CN and water solution, and characterized by elemental analysis, IR spectra and UV spectra. The results suggest that the organic molecules combine a H⁺ first and then form the charge transfer salts. There is a strong interaction between anion and the organic cation in solid state. The charge-transfer in the compound will take place under irradiation of light and the anion will be reduced in one -electron step. The heteropoly blue were formed after the charge transfer salts were irradiated under light. The results of the second-order and third nonlinear optical properties indicate that both of them increased as the increasing of the tungsten in the molecules.

Keywords: heteropoly acid N-methylpyrolinedone second-order nonlinear optical property
