Abstract

By using terephthalic acid, 2, 5-furandicarboxylic acid, and terbium nitrate hexahydrate, a Tb-MOF with a core-shell structure was successfully designed and prepared. A one-pot method was employed to design and synthesize core-shell Tb-MOF. The morphology, luminescence performance, and stability were well characterized. Tb-MOF demonstrated good water stability, acid and alkali resistance, and thermal stability. Tb-MOF was found to have high sensitivity to detect Cr3+, Bi3+, and acetone in an aqueous solution, and the LOD of Cr3+, Bi3+, and acetone were calculated to be 0.18 μM, 4.22 μM, and 0.26%, respectively. The sensing mechanism of Cr3+ and acetone was explained as energy-competitive absorption, and the sensing mechanism of Bi3+ was explained as ion replacement. The prepared Tb-MOF can be developed as a multifunctional light-emitting sensor with high selectivity.

利用核壳 Tb-MOF 对水溶液中的 Cr3+、Bi3+ 和丙酮进行发光检测

利用对苯二甲酸、2，5-呋喃二甲酸和六水合硝酸铽，成功设计并制备了核壳结构的Tb-MOF。Tb-MOF对水溶液中的Cr3+、Bi3+和丙酮具有较高的检测灵敏度，Cr3+、Bi3+和丙酮的LOD分别为0.18 μM、4.22 μM和0.26%。Cr3+和丙酮的感应机制被解释为能量竞争吸收，Bi3+的感应机制被解释为离子置换。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
