Two novel lanthanide metal‐organic frameworks (LnMOFs), Ln1.14Na0.57(BDC)2(H2O) ⋅ 4H2O (Ln=La3+ or Ce3+, BDC : 1,3‐benzenedicarboxylate), have been synthesized under hydrothermal conditions by using a Ln3+ coordination polymer as precursor. The crystal structure was determined from single crystal X‐ray diffraction. Both compounds are isostructural and contain chains of face‐sharing [LnO10] polyhedra connected by the linkers to form an anionic three‐dimensional network, defining both polar and apolar channels, the latter being occupied by water molecules and Ln3+ and Na+ cations. When doped by optimized content of Eu3+ and Tb3+, the La3+ counterpart exhibits white luminescence emission with CIE parameters equal to (0.3440, 0.3735) at λexc=321 nm, which renders the material attractive for white LED application.

镧系间苯二甲酸金属有机骨架：晶体结构，热行为和白色发光
已经开发出两种新型的镧系金属有机骨架（LnMOF）：Ln 1.14 Na 0.57（BDC）2（H 2 O）⋅4H 2 O（Ln = La 3+或Ce 3+，BDC：1,3-苯二甲酸）以Ln 3+配位聚合物为前体在水热条件下合成。晶体结构由单晶X射线衍射确定。两种化合物都是同构结构，并包含通过连接子连接的共享面部[LnO 10 ]多面体链，形成一个阴离子三维网络，定义了极性和非极性通道，后者被水分子以及Ln 3+和Na占据+阳离子。当由铕优化的内容掺杂3+和Tb 3+的La 3+对方表现出与CIE参数白色发光发射等于（0.3440，0.3735）在λ EXC = 321纳米，这使得对于白色LED应用的材料的吸引力。
