摘要

以1,3,5-苯三羧酸酯和1,3-双(咪唑)丙烷与硝酸锌在DMAc - h2o (DMAc为N,N-二甲基乙酰胺)中溶剂热组装得到了一种新的锌(II)金属有机骨架，即{[zn2 (μ 2 -OH)(1,3- bip)(BTC)]·DMAc·2h2o} N (SNUT-6)。通过单晶和粉末x射线衍射、红外光谱、热重分析和元素分析对产品进行了表征。单晶x射线衍射表明，SNUT-6呈现3D→3D双重互穿骨架结构。此外，SNUT-6对甲醇中的苯胺具有高效的关闭荧光检测能力，ksv值为4.771 × 10.4 M−1，灵敏度高。对罗丹明b、甲基橙和甲基蓝三种染料分子模型也表现出优异的光催化降解性能。

A two-fold interpenetrated Zn(II) organic framework based on mixed ligands: Synthesis, crystal structure, and properties

A new zinc(II) metal organic framework has been obtained from the solvothermal assembly of 1,3,5-benzene tricarboxylate and 1,3-bis(imidazole)propane with zinc nitrate in DMAc–H 2 O (DMAc is N,N-dimethylacetamide), namely {[Zn 2 (μ 2 -OH)(1,3-BIP)(BTC)]·DMAc·2H 2 O} n (SNUT-6). The product is characterized by single-crystal and powder X-ray diffraction, infrared spectroscopy, thermogravimetric analysis, and elemental analysis. The single-crystal X-ray diffraction reveals that SNUT-6 exhibits a 3D→3D two-fold interpenetrating framework. Furthermore, SNUT-6 demonstrates a highly efficient turn-off fluorescent detection ability for aniline in methanol and shows high sensitivity with a K sv value of 4.771 × 10 4 M −1 . It also shows excellent photocatalytic degradation performance for a three-dye molecular model: rhodamine b, methyl orange, and methyl blue.

期刊介绍： The Journal of Chemical Research is a monthly journal which has a broad international authorship and publishes research papers and reviews in all branches of experimental chemistry. Established in 1977 as a joint venture by the British, French and German chemical societies it maintains the high standards set by the founding societies. Each paper is independently peer reviewed and only carefully evaluated contributions are accepted. Recent papers have described new synthetic methods, new heterocyclic compounds, new natural products, and the inorganic chemistry of metal complexes.
