摘要: 在溶剂热条件下,以H2(3-PDCA)配体、BIPY配体和Cu(NO32·3H2O为反应物,构筑了两例新型Cu(Ⅱ)配位聚合物(简称:配合物):[Cu2(H2O)3(3-PDCA)2]·2H2O(1)和{[Cu2(BIPY)(3-PDCA)2]·H2O} n2)。其中,H2(3-PDCA)为1-(3-羧基苯基)-5-甲基-4-氧代-1,4-二氢吡嗪-3-羧酸,BIPY为4,4'-联吡啶。铝离子(Al3+)的环境毒性及其检测需求促使本研究开发基于配合物的荧光探针。X射线单晶衍射表明:配合物1呈现特殊的四节点环状结构,配合物2呈现有趣的六节点菱形二维结构。PXRD、FT-IR和TGA证实了两种配合物的结构完整性。固体荧光测试表明,配合物1对Al3+具有高选择性检测能力,检出限低至2.11×10-5 mol·L-1,优于多数同类材料。配合物1可作为一种高效Al3+荧光传感器,为环境监测提供新策略。

Abstract: Under solvothermal conditions, two novel Cu(Ⅱ) coordination polymers (abbreviated as complex) were constructed by 1-(3-carboxyphenyl)-5-methyl-4-oxo-1,4-dihydropyridazine-3-carboxylic acid abbreviated as H2(3-PDCA), 4,4'-bipyridine (BIPY) ligand and Cu(NO32·3H2O: [Cu2(H2O)3(3-PDCA)2]·2H2O (1) and {[Cu2(BIPY)(3-PDCA)2]·H2O} n2). The environmental hazards of Al3+ drive the development of fluorescent probes based on coordination polymers. Single-crystal X-ray diffraction reveals that complex 1 adopts a four-node ring structure, while complex 2 exhibits a six-node rhombic 2D network. Their structural integrity was confirmed by PXRD, FT-IR, and TGA. Solid-state fluorescence studies demonstrate that complex 1 acts as a highly selective sensor for Al3+ with a detection limit of 2.11×10-5 mol·L-1, surpassing most reported materials. This work highlights the potential of complex 1 as an efficient Al3+ fluorescent probe for environmental monitoring.
