(L(I)) and 1,1,1-tris[(2'-furfurylaminoformyl)phenoxyl]methyl}ethane (L(II)) have been designed and synthesized with the ultimate aim of self-assembling lanthanide polymers with interesting luminescent properties. Among two series of Ln(III) nitrate complexes (Ln = Pr, Nd, Sm, Eu, Gd, Tb or Dy) which have been characterized by elemental analyses, XRD, TGA and IR spectra, three new coordination polymers
两个新的与结构相关的三脚架配体,具有水杨酰胺悬垂臂,1,3,5-tris [((2'-糠基氨基甲酰基)苯氧基]甲基} -2,4,6-三甲基苯(L(I))和1,1, 1-tris [((2'-糠基氨基甲酰基)苯氧基]甲基}乙烷(L(II))已被设计和合成,其最终目的是自组装具有有趣发光性能的镧系元素聚合物。在通过元素分析,X射线衍射,热重分析和红外光谱表征的两个系列的硝酸Ln(III)硝酸盐配合物(Ln = Pr,Nd,Sm,Eu,Gd,Tb或Dy)中,已经确定了三种新的配位聚合物X射线衍射分析。配位聚合物类型[Ln(NO(3))(3)(L(I))。nH(2)O}(n)具有不寻常的梯状双链,可以通过pi-pi堆积相互作用进一步连接构造三维超分子结构。相反,配位聚合物类型[Ln(NO(3))(3)(L(II))]。nCH(3)OH}(n)显示连接(3,3)的褶皱二维网络具有4.8(2)
