The reactions of lanthanide nitrates with 5-nitroisophthalic acid (ab. 5-H(2)nip) in DMF and ethanol (1 : 1) mixed solution gave rise to three nanoporous lanthanide polymers, {Ln(2)(5-nip)(3)(DMF)(4)(2)}(n) (Ln = Nd (), Dy (), Ho (), 5-nip = 5-nitroisophthalate). Single-crystal X-ray diffraction analyses reveal that they are isomorphous and feature three-dimensional metal-organic frameworks with two-dimensional intersecting channels occupied by guest DMF molecules constructed from the linkage of dimer Ln(2)C(6)O(12) SBUs and 5-nip ligands. The guest DMF molecules can be reversibly removed from as identified using TGA-DSC and PXRD. The heat of adsorption of the guest-free sample of with DMF was measured with a value of 10.3 kJ mol(-1) by an RD496-III type microcalorimeter. In addition, the photoluminescent property of was investigated.
镧系硝酸盐与 5-硝基间苯二甲酸（简称 5-H(2)nip）在 DMF 和乙醇（1:1）混合溶液中的反应生成了三种纳米多孔镧系聚合物，{Ln(2)(5-nip)(3)(DMF)(4)(2)}（n）（Ln = Nd (), Dy (), Ho ()，5-nip = 5-硝基间苯二甲酸根）。单晶 X 射线衍射分析表明，它们是同构的，具有由连接体 Ln(2)C(6)O(12) SBUs 和 5-nip 配体构建的二维交叉通道的三维金属-有机骨架。通过 TGA-DSC 和 PXRD 可以鉴定出客体 DMF 分子的可可逆去除。用 RD496-III 型微量量热计测量了无客体 DMF 的样品的吸附热，吸附热为 10.3 kJ mol(-1)。此外，还研究了的光致发光性质。
