通过光解液的 Mo K 边缘 XAFS 光谱监测在 pH 3.4 下 UV 诱导的 [Mo 7 O 24 ] 6 至 28 电子还原 {Mo 142 } 的自组装。 EXAFS曲线拟合分析表明，与{Mo 8 }平衡的[MoO 4 ] 2-的积累伴随着双电子还原的{Mo 14 }的形成，并且随后构建的[Mo 20 }和{Mo 21 }结构单元通过还原缩合提供了IMo 142 }。
The UV-induced self-assembly of [Mo 7 O 24 ] 6- to 28-electron-reduced {Mo 142 } at pH 3.4 was monitored by Mo K-edge XAFS spectra of photolytes. The EXAFS curve fit analysis indicates that the accumulation of [MoO 4 ] 2- in an equilibrium with {Mo 8 } was accompanied by the formation of two-electron-reduced {Mo 14 }, and the subsequent construction of the [Mo 20 } and {Mo 21 } building blocks provided IMo 142 } through their reductive condensation.
