Structural characterization of 4-(4-carboxyphenoxy)phthalate-based Cd2+ and Mn2+ coordination polymers are reported, and Cd2+ coordination polymer can serve as probe to sense nitrobenzene.
single-crystal X-ray diffraction. The results indicate that in compound 1, the H3L1 ligands adopt bis-monodentate coordination mode to connect the two kinds of 1D Ni-4,4′-bipy-Ni chains, giving a 3D network with rare (42·63·8)2(6·84·10) topological structure. In compound 2, H3L2 ligand acts as the terminal mode while the 4,4′-bipy ligands bridge the Ni(II) ions to generate infinite Ni-4,4′-bipy-Ni zig-zag chains
摘要 三种新的 3D 金属有机骨架 (MOF) [Ni3(L1)2(4,4'-bipy)4(H2O)6]∙6H2O (1), [Ni(HL2)(4,4'-bipy) (H2O)3]∙(4,4'-bipy) (H2O) (2) 和 [Mn3(L2)2(H2O)(DMF)2] (3) 基于半刚性 V 形配体,4 -(4-羧基苯氧基)邻苯二甲酸(H3L1)和3-(4-羧基苯氧基)邻苯二甲酸(H3L2),已在水热和溶剂热条件下成功合成,并通过元素分析、热学研究以及粉末和单-晶体 X 射线衍射。结果表明,在化合物1中,H3L1配体采用双-单齿配位模式连接两种一维Ni-4,4'-bipy-Ni链,形成具有稀有(42·63·8)2的3D网络(6·84·10)拓扑结构。在化合物 2 中,H3L2 配体作为终端模式,而 4,4'-bipy 配体桥接 Ni(II) 离子以生成无限的 Ni-4,4'-bipy-

grid-like supramolecular layer network. The π⋯π interactions between the bpy molecules are observed between the supramolecular layers; (iii) in compound 3, two hydroxylimino groups for the dcpth I moleculeslink first the Zn2+ ions into a dimer, which can be viewed as a tetrahedral node. The dcpth II molecules act as the linkers, extending the tetrahedral nodes into another 1-D double-chain structure,

4-butanediyl)bis(imidazole)) have been synthesized and characterized by elemental analysis (EA), infrared spectra (IR), X-ray powder diffraction (XRPD), solid fluorescence and thermogravimetric analysis (TGA). Single-crystal X-ray diffraction analysis revealed that complex I possesses a 3D self-penetrating frameworkconstructedfrom ladder-like and fishbone-like subunits. Complex II shows a 3Dframework of two-fold
两个新的有趣的纠缠结构,即[Ni 1.5(L)(bpy)2(H 2 O)3 ] n ·3 n H 2 O(I)和[Cd 3(L)2(bbi)2 ] n · n H 2 O(II)(其中H 3 L是4-(4-羧基苯氧基)-邻苯二甲酸,bpy是4,4'-联吡啶,bbi是1,1'-(1,4-丁二基)双(咪唑)),并通过元素分析进行了表征(EA),红外光谱(IR),X射线粉末衍射(XRPD),固体荧光和热重分析(TGA)。单晶X射线衍射分析表明,复合物I具有3D自穿透框架,该框架由梯形和鱼骨形亚基构成。配合物II显示了由bbi和L 3-配体桥接的三核Cd(II)簇组装而成的两重互穿的3D框架。

was stable in aqueous solutions with pH values of 4-10. The Zn-MOF exhibited a strong emission band centered at 385 nm owing to the π*→π electron transition of the ligand. It showed high luminescence in some common organic solvents as well as in the aqueous solutions of pH 4-10. Interestingly, TC and acetone effectively quenched the luminescence of the Zn-MOF in aqueous solution and enabled the Zn-MOF
