| 摘要: 以1，3，5-三（4-羧基苯基）苯（H3BTB）为配体，通过溶剂热法得到一种三维四重穿插结构的镉基金属有机骨架材料：（Me2NH2）[Cd（BTB）（DMF）]·DMF·H2O（Cd-MOF）。通过单晶X射线衍射、粉末X射线衍射、红外分析、元素分析和热重分析表征了其组成和结构。荧光研究结果表明：Cd-MOF在含有丙酮或Fe3+离子的溶液中均表现出荧光猝灭现象，其检测限（体积分数和浓度）分别为0.6%和0.89 μmol·L-1，线性检测范围分别为2.0%~2.8%和0~0.05 mmol·L-1。时间响应实验和可循环利用实验显示Cd-MOF可长时间、稳定且高效地检测丙酮和Fe3+离子。 | |

| Abstract: A Cd-based metal-organic framework with the formula (Me2NH2)[Cd(BTB)(DMF)]·DMF·H2O (Cd-MOF) has been synthesized via the solvothermal method using 1, 3, 5-tris(4-carboxyphenyl)benzene (H3BTB) as a ligand, and its structure was characterized by single crystal X-ray diffraction, powder X-ray diffraction, elemental analysis, and thermogravimetric analysis. It could selectively detect acetone and Fe3+ ions by fluorescence quenching with the detection limits (volume fraction and concentration) of 0.6% and 0.89 μmol·L-1, respectively. The linear detection ranges of 2.0%-2.5% for acetone and 0-0.05 mmol·L-1 for Fe3+ ions were observed. Time response and recyclability experiments confirmed that Cd-MOF is a reliable and efficient fluorescence sensor for the long-term detection of acetone molecules and Fe3+ ions. | |
