摘　　要：以Dawson结构杂多酸(D HPA)为氧化剂、质子酸和掺杂剂,制备了高纯度的P2Mo18/PANI(S1)和P2Mo17V/PANI(S2)电子聚合物材料.用红外光谱、紫外 可见光谱及X 射线粉末衍射等手段进行了表征,测定了材料的导电性和荧光性.讨论了HPA氧化苯胺法的聚合机理.结果表明:该材料是D HPA掺杂的PANI杂化材料.材料的导电率分别为σS1=5.50×10-3和σS2=1.10×10-1S·cm-1.当S1和S2的激发光波长分别为423和363nm时,其对应的荧光发射光的波长为521和434nm.这表明S1和S2为电子聚合物材料.P_2Mo_(18)/PANI(S_1) and P_2Mo_(17)V/PANI(S_2) electron polymer materials were prepared by using Dawson structure heteropolyacid (D-HPA) as proton acid, oxidizer and depart. These materials were characterized by IR spectra, UV-Vis and XRD spectra. Their conductivity and fluorescence spectrophotometry were determined. The mechanism of polymerization and doping were investigated. The results show that conductivity of the materials were (5.50×10^(-3) (S_1)) and 1.10×10^(-1) S·cm^(-1)(S_2). The fluorescence property is λ_(ex)=423,λ_(em)=521 nm for S_1;and λ_(ex)=363,λ_(em)=434 nm for S_2.
