Abstract

An organic-inorganic hybrid polyoxometalate (POM) based on bi-nuclear copper complexes and Dawson-type phosphotungstate (POT) [CuL(H₂O)][CuL]₂[P₂W₁₈O₆₂]·3H₂O (abbreviated as CPW) (L = 2-(1H-pyrazol-3-yl)pyridine) was synthesized and structurally characterized by IR spectrum, and single-crystal X-ray diffraction. Structural analysis indicated that CPW is nanoscale molecule and extends into a two-dimensional layer, in which three bi-nuclear copper complexes are substituted at different sites of Dawson-type POT and joined adjacent POT fragments together. Notably, CPW can efficiently catalyze the production of reactive oxygen species.

摘要

基于双核铜配合物和道森型磷钨酸盐（POT）[CuL（H ₂ O）] [CuL] ₂ [P ₂ W ₁₈ O ₆₂ ]·3H ₂ O的有机-无机杂化多金属氧酸盐（POM）（缩写）如CPW）（L ＝ 2-（1 H-吡唑-3-基）吡啶）的化合物被合成并通过IR光谱和单晶X射线衍射进行结构表征。结构分析表明，CPW是纳米级分子，并延伸到二维层，其中三个双核铜络合物在Dawson型POT的不同位置被取代，并将相邻的POT片段连接在一起。值得注意的是，CPW可以有效地催化活性氧的产生。
