Isostructural redox-active ionic crystals were synthesized with large-molecular-size and easily reducible α-Dawson-type polyoxometalates [α-PMO] (M = Mo and W) as building blocks. The crystals possess large closed pores and show rapid (1 h) and large amounts (5.5 or 4.4 mol mol) of Cs uptake at room temperature via reduction of the polyoxometalates. The reduced compounds can be fully oxidized, and Cs is released within 10 min.
采用具有大尺寸分子和易还原的 α-Dawson 型多金属氧酸盐 [α-PMO]（M = Mo 和 W）作为构筑块，合成了同结构的氧化还原活性离子晶体。这些晶体具有较大的封闭孔道，室温下通过多金属氧酸盐的还原，可快速（1 h）和大量（5.5 或 4.4 mol mol）地吸收 Cs。还原后的化合物可以完全被氧化，并且在 10 min 内释放出 Cs。
