Three isomorphic pendant derivatives based on monovacant Keggin heteropolytungstate [SiW11O39]8- as building block have been synthesized through the decoration of Co-Im complexes using bench method:5Na_4H_2[SiW_(11)O_(39)CoIm]_(0.63)[SiW_(11)O_(39)Co(H_2O)]_(0.37)·7H_2O (1)_6[SiW_(11)O_(39)NiIm]_(0.8)[SiW_(11)O_(39)Ni(H_2O)]_(0.2)·7H_2O (2)_4Na_6[SiW_(11)O_(39)MnIm]_(0.69)[SiW_(11)O_(39)Mn(H_2O)]_(0.31)·7.5H_2O (3) Complexes 1–3 are the first examples of crystallographically characterized 3d-transition metal mono-substituted POMs with an antenna organic ligand synthesized under normal bench conditions.

以单缺位Keggin型杂多钨硅酸盐[SiW11O39]8-为建筑单元，在水溶液中通过过渡金属-咪唑配合物的修饰，成功地获得了三个同构的悬臂式衍生物：5Na_4H_2[SiW_(11)O_(39)CoIm]_(0.63)[SiW_(11)O_(39)Co(H_2O)]_(0.37)·7H_2O (1)_6[SiW_(11)O_(39)NiIm]_(0.8)[SiW_(11)O_(39)Ni(H_2O)]_(0.2)·7H_2O (2)_4Na_6[SiW_(11)O_(39)MnIm]_(0.69)[SiW_(11)O_(39)Mn(H_2O)]_(0.31)·7.5H_2O (3)它们是第一例在常规水溶液条件下合成得到的X-射线表征的3d-过渡金属取代的悬臂式多酸衍生物。

On the one hand, POMs have a very strong, approaching the superacid region, Br?

杂多酸是一种很强的Br？

POMs and deys are still maintained integrallty.AFM exhibits the films is even.The thickness of each layer is about 1.25nm. The AFM images reflect that there are some protuberances on the outer surface layer of the film, which due to the aggregates of spherical structure PMo12. Cyclic Voltammograms reflects the redox potentials of dye in multilayer shifts towards more positive values than pure dye multiplayer which may be explained by charge transfer from dye to POM. Fluorescence spectra show that polyoxometalates caused the fluorescence decay of dyes, which maybe used as fluorescence sensors.

UV-VIS说明复合膜均匀生长； IR 光谱、XPS能谱研究结果表明，紫外光照前后，膜中多酸/染料分子间没有发生显著的光化学反应，各组分的结构仍然保持；原子力显微镜显示，膜的外表面是均匀的，每一个双层厚度大约是1.25nm，膜表面的隆起，可能是多酸阴离子簇堆积所引起；循环伏安测定结果表明，由于多酸阴离子的影响，有机染料的氧化还电位发生了正的偏移，反映出复合膜中染料分子与多酸阴离子间发生了荷移相互作用，导致染料分子失去部分电子而使氧化性略强；荧光光谱研究结果表明，多酸阴离子可以有效地引发荧光染料的荧光淬灭，这为多酸在荧光传感器方面的应用提供了有价值的信息。

There are some methods used commonly to immobilize POM on electrode surface, for example, electrodeposition of POMs on the electrode surface from a polyoxometalates solution under constant potential, self-assembly and layer-by-layer deposition, entrapment POM into polymers matrics and sol-gel method. There are some drawbacks using above methods.

杂多酸化学修饰电极主要有以下几个方法：恒电势下，多酸阴离子在电极表面的电沉积；多酸阴离子在电极表面的自吸附；聚电解质和多酸阴离子在电极表面的交替沉积；把多金属氧酸盐包埋在各种聚合物中；溶胶－凝胶法。

In view of the extensive contemporary interest in POMs, the work is both timely and significant.
