In this paper, we report the successful assembly of achiral {Ln6M} ([Ln6M(μ3-OH)8(acac)12(CH3O)x(CH3OH)y], Ln = La, M = Mn, Co, Fe) and chiral {Nd9Fe2} ([Nd9Fe24-O)(μ3-OH)14(acac)16(NO3)(CH3OH)2(H2O)3]) rare earth clusters using achiral rigid ligands and a transition metal doping strategy. {Ln6M} can be viewed as the fusion of two {Ln3M} tetrahedrons by sharing vertices. {Nd9Fe2} results from the fusion of four {Ln3M} tetrahedrons by vertice and edge sharing. The substitution of Ln with transition metal leads to changes in the coordination pattern around neighboring Ln, which triggers the switch of metal center chirality. This study demonstrates the potentiality of utilizing transition metal doping and rigid ligand to control the chirality of rare earth clusters. In addition, the photocatalytic CO2 activity of these transition metal-doped rare earth clusters has been studied.

掺杂过渡金属调节稀土簇的手性和光催化活性

在本文中,我们报道了非手性{Ln 6 M} ([Ln 6 M(μ 3 -OH) 8 (acac) 12 (CH 3 O) x (CH 3 OH) y ],Ln = La, M = Mn、Co、Fe) 和手性 {Nd 9 Fe 2 } ([Nd 9 Fe 24 -O)(μ 3 -OH) 14 (acac) 16 (NO 3 )(CH 3 OH) 2 ( H 2 O) 3 ]) 使用非手性刚性配体和过渡金属掺杂策略的稀土簇。{Ln 6 M}可以看作是两个{Ln 3 M}四面体通过共享顶点的融合。{Nd 9 Fe 2 }由四个{Ln 3 M}四面体通过共享顶点和边融合而成。Ln被过渡金属取代会导致邻近Ln周围的配位模式发生变化,从而触发金属中心手性的转换。这项研究证明了利用过渡金属掺杂和刚性配体来控制稀土簇的手性的潜力。此外,还研究了这些过渡金属掺杂稀土簇的光催化CO 2活性。
