| 摘要: 以 1，4，5，8-萘四羧酸为原料，在溶剂热条件下原位反应合成得到一个具有 3D 拓扑结构的发光钡基金属有机骨架(MOF)：[Ba(dna)(H2O)2]n(1，H2dna=1，8-萘二甲酸酐-4，5-二羧酸)，并通过单晶X射线衍射、元素分析、热重分析和粉末X射线衍射技术对其进行表征。结构分析表明，1包含一个π共轭基团和酸酐基团的有机配体dna2-，荧光和紫外研究表明其能灵敏地检测溶液中的芳香胺，可能是MOF结构中配体的酸酐基团和氨基之间的反应驱动的，这大大提高了荧光发射强度，并达到裸眼可见的颜色变化。此外，以配合物1为前驱体在中等温度下直接煅烧制得了单一晶型的纳米BaCO3颗粒。 | |

| Abstract: Using 1,4,5,8-naphthalene tetracarboxylic acid as a raw material, a luminescent barium-based metalorganic framework (MOF), [Ba(dna)(H2O)2]n (1, H2dna=1,8-naphthalic anhydride-4,5-dicarboxylic), with a 3D topological structure was synthesized by in situ reaction under solvothermal conditions, and characterized by single-crystal X-ray diffraction, elemental analysis, thermogravimetric analysis, and powder X-ray diffraction. The structural analysis demonstrates that it has the underlying 3D topology, encompassing a π-conjugated organic ligand with an anhydride group. It exhibited a low detection limit for aromatic amines in an aqueous solution, which may be driven by an anhydride amine reaction between the ligand and the hosted amines, with a significant enhancement of the emission intensity and visual color change. Furthermore, micro-crystalline BaCO3 particles can be prepared through direct calcination of complex 1 as a precursor at moderately elevated temperatures. | |
