To confirm how different anions influence sup-ramolecular self-assembly of lanthanide-organic frameworks (LnOFs) as well as their luminescent properties, a new flexible achiral tripodal ligand, 1,1,1-tris-{[(2'-benzylaminoformyl)phenoxyl]methyl}ethane (L) and the LnOFs {[EuL(NO(3))(3)]·1.5CHCl(3)}(n) and EuL(pic)(3) have been designed and assembled. In the two LnOFs, {[EuL(NO(3))(3)]·1.5CHCl(3)}(n) demonstrates an unprecedented chiral noninterpenetrated two-dimensional (2D) honeycomblike (6,3) (hcb, Schläfli symbol 6(3), vertex symbol 6·6·6) topological network, and EuL(pic)(3) confirms an unusual chiral LnOF with three-dimensional (3D) (10,3)-a (srs, SrSi(2), Schläfli symbol 10(3), vertex symbol 10(2)·10(4)·10(4)) topological framework. Also the anion-induced structures and energy transfer processes in the luminescence behavior of the two LnOFs were discussed in detail.
为了确认不同的阴离子如何影响镧系有机框架（LnOFs）的超分子自组装及其发光性质，设计并组装了一种新的柔性手性三齿三脚架配体 1,1,1-tris-｛[(2'-苄基氨基甲酰基)苯氧基]甲基｝乙烷（L）以及 LnOFs{[EuL（NO3）（3）]·1.5CHCl3}（n）和[EuL（pic）（3）]（n）。在这两个 LnOFs 中，{[EuL（NO3）（3）]·1.5CHCl3}（n）展示了前所未有的手性非穿插二维（2D）蜂窝状（6,3）（hcb，Schläfli 符号 6(3)，顶点符号 6·6·6）拓扑网络，而[EuL（pic）（3）]（n）则证实了具有三维（3D）（10,3）-a（srs，SrSi(2)，Schläfli 符号 10(3)，顶点符号 10(2)·10(4)·10(4)）拓扑结构的不寻常手性 LnOF。还详细讨论了两种 LnOFs 中发光行为中阴离子诱导的结构和能量转移过程。
