摘　　要：以乙二胺(EDA)为中心核、三羟甲基丙烷三丙烯酸酯(TMPTA)为原料,合成端基为8个伯胺基的树枝状聚(胺-酯)[PAE(NH2)8],再与杂多酸阴离子[Mo6O19]2-作用,基于静电组装得到多金属氧簇阴离子[Mo6O19]2-/PAE树枝状聚(胺-酯),产率为77%。用红外光谱、紫外光谱、热重分析、荧光光谱等表征了它的结构及性能测试。并将其修饰在碳电极的表面,用循环伏安法研究了多金属氧簇阴离子/树枝状聚(胺-酯)修饰碳电极的电化学行为和电催化性能。结果表明,该化合物具有良好的荧光性能,用该化合物修饰的石墨电极与[Mo6O19][N(C4H9)4]2修饰的石墨电极相比,在-0.2～0.2V范围内多了1对氧化还原峰,对H2O2、NaNO2的分解具有良好的电催化活性,对KClO3的分解则无明显催化活性。The terminal group of which are 8 primary amine dendrite poly（amine-ester） （PAE） was synthesized from ethyl enediamine （EDA） and trimethylolpropane triacrylate （TMPTA）, then a novel supramolecular compound [Mo6O19]2-/PAE assembled by ionic bonding was synthesized by dendric poly（amide amine） [PAE（NH2 ）8] and EMo601922- polyanion, the yield was 77%. The [Mo6O19]2-/PAE was characterized by FTIR, UV, TGA and fluorescence spectrum. Its modification in the carbon electrode surface was studied by cyclic voltammetry with polyoxometalate cluster anion/dendritic poly（amine-ester） modified carbon electrode and electrochemical behavior and electrocatalytic properties. The results show that the title compound exhibits good fluorescence. One more pair of redox peaks is observed in a potential range of --0. 2--0. 2V with carbon electrode modified by [Mo6O19]2-/PAE with the redox peaks of carbon electrode modified by [Mo6O19]2-/[N（C4Hg）4]2-. It shows good electroeatalytic activity toward the reductions of H2O2 and NaNO2, but no electrocatalytic activity toward the reductions of KClO3.
