Keggin型聚氧乙烯酸盐（POM）与含有低聚（环氧乙烷）单元的二铵离子的自组装形成平行六面体或八面体纳米晶体。这些结构是可调的，这取决于铵离子的化学结构和制备条件。这些铵离子中的醚键发挥构象的灵活性，这是必不可少的，以实现在纳米晶体中的长程规则的分子排列。
Self-assembly of Keggin-type polyoxometalates (POMs) with diammonium ions containing oligo(ethylene oxide) units form parallelepiped or octahedral nanocrystals. These structures are tunable depending on the chemical structure of the ammonium ions and preparative conditions. The ether linkages in these ammonium ions exert conformational flexibility, which is essential to achieve long-range regular molecular alignments in the nanocrystals.
