| 摘 要： | 以3,3''，5,5''-四-（羧基苯基）联苯为配体（H4L），与镧系金属Ln（Ⅲ）盐反应，自组装形成了5个具有三维孔洞结构的镧系金属-有机框架材料：{[Ln3L2(H2O)7]·(OH)·10DMA}n(Ln=Gd (1a); Ln=Ho(2a), {[Ln3L2(H2O)3]·(OH)·mDMA}n (Ln=Er，m=10(1b); Ln=Yb, m=9(2b); Ln=Lu, m=10(3b))。单晶X射线衍射分析表明，这些MOFs属于2种系列的类质同晶化合物，分别属于正交晶系Ccca空间群和单斜晶系C2/c空间群。有机小分子溶剂交换荧光研究发现，2b对小分子二氯甲烷和甲苯荧光有增强效应，表现出良好的荧光探测功能。

| Abstract: | Biphenyl-3,3'',5,5''-tetra-(phenyl-4-carboxylic acid) (H4L) was used to synthesize five microporous three-dimension metal-organic framework with lanthanide metal matrix by intermolecular self-assembly, namely, {[Ln3L2(H2O)7]·(OH)·10DMA}n (Ln=Gd (1a); Ln=Ho (2a)), and {[Ln3L2(H2O)3]·(OH)·mDMA}n (Ln=Er, m=10(1b), Ln=Yb, m=9(2b), Ln=Lu, m=10(3b)). Single-crystal X-ray diffraction revealed the Ln-MOFs are two series of isomorphous metal-organic frameworks, and belong to orthorhombic Ccca space group and monoclinic C2/c space group, respectively. The luminescence intensity of 2b can be modulated by organic small molecule solvents, and 2b exhibited the enhancement of the luminescence intensity when dispersed in CH2Cl2 and toluene. |
