代替 monomolybdenum 的 Keggin 类型 polyoxometalates 的电气化学的行为[XW11MoO40 ] n？(X=P， Si，有 n=3 的 Ge， 4 ) 被学习在水并且 N， N-dimethylformamide (DMF ) 答案。这些 anionic 簇在二种媒介显示出不同电气化学的行为。起始的潜力[XW11MoO40 ] n？在 DMF 是比在水的答案的那些更否定的，显示出一个更低的氧化能力[XW11MoO40 ] n 吗？在 DMF。调查结果建议 polyoxometalates 的氧化还原作用性质被瞬间的替换为 W 并且由用器官的溶剂代替水的答案调节，它提供了珍贵信息讲道理地在基于 POM 的器官 / 无机的混合材料的准备选择 polyoxometalates (POM ) 。

英文摘要：

The electrochemical behavior of monomolybdenum-substituted Keggin-type polyoxometalates [XW11MoO40]^n- （X=P, Si, Ge with n=3, 4） was studied in aqueous and N,N-dimethylformamide （DMF） solution. These anionic clusters showed different electrochemical behaviors in two kinds of media. The initial potentials of [XW11MoO40]^n- in DMF were more negative than those in aqueous solution, showing a lower oxidation ability of [XW11MoO40]^n- in DMF. The investigation results suggested that the redox properties of polyoxometalates be tuned by the substitutions of Mo for W and by replacing aqueous solution with organic solvent, which provided valuable information to rationally choose polyoxometalates （POM） in preparation of POM-based organic/inorganic hybrid materials.
