2024年5月1日 · By modifying the electron-deficient bipyridinium to contain carboxylic acid moieties and coordinating them with the luninescent Eu 3+ ion, a unique and versatile Eu-MOF has been synthesized. Under UV light conditions, the complex shows an obvious color change from colorless to blue, which is due to the formation of viologen radicals after ...

2016年11月4日 · Europium metal organic framework (Eu-MOF) was synthesized using Europium as metal ion center and 1,3,5-trimesic acid (H3BTC) as organic ligand under hydrosolvothermal conditions.

2024年7月21日 · Eu-MOF显示出基于Eu离子和(dpa)配体通过μ: η, η, η, η配位模式的三维网络结构。 荧光分析表明，Eu-MOF具有优异的荧光传感特性，可以高效、灵敏地检测水中的各种污染物：比率荧光检测水中ANI的检测限（LOD）为42.9 nM，优于单分子荧光法。

2021年3月15日 · A novel cluster-based Eu-MOF was successfully synthesized, which shows excellent stability including in acidic and basic water solutions and boiling water for 15 days. 1 with bright fluorescence shows sensitive and selective detection for MDZ and DMZ in aqueous solution with the low detection limit (ppm), and it can also be used as a ...

2024年5月14日 · 与过渡金属MOFs相比，镧系MOFs（Ln-MOF）具有许多优势，例如高且可变的配位数目、灵活的配位几何结构和由4f电子跃迁产生的独特光电特性。 此外，Ln-MOFs可以显示更大的斯托克斯位移、高量子效率、固定的荧光寿命和良好的荧光单色性。

2023年12月15日 · Here, we develop a portable, sensitive, and stable (Eu-MOF)-based sensing platform to detect miRNA via smartphone. The Eu-MOF absorbs the carboxyfluorescein (FAM)-tagged probe DNA (pDNA) to generate hybrid pDNA@Eu-MOF, which can efficiently quench the fluorescence of FAM through a photoinduced electron transfer (PET) process.

2018年12月13日 · 金属-有机框架（metal-organic framework，MOF，也称“金属-有机骨架”）是近年来另一类颇受关注的新型材料，在气体吸附分离、催化、药物输运等领域有着很大的应用潜力。 也有科学家将MOF做成了凝胶材料，但实际上，要么是先合成MOF纳米颗粒然后通过配位进行错配生长和凝胶化，要么用聚合物基质包埋纳米级MOF，严格意义上来说它们都属于“MOF-凝胶混合物”，很难称之为真正的“MOF凝胶”。 大家都知道MOF是由金属离子（或团簇）与有机配体组装 …

2025年2月5日 · Herein, QIPA-Eu-1 and QIPA-Eu-2 isomers were prepared from QIPA and EuCl 3 ·6H 2 O in different solvent thermal conditions for building sequential stimuli-response (SSR) system. Solvent-driven structural transformations of the isomers into QIPA-Eu-3 occurred, along with color change and fluorescence emission variation ascribed to the ...

本文成功合成了一种新型的eu-mof（zl-1），并揭示了其自ecl机制，包括n-h键的断裂、两步电还原过程以及hncp配体至eu3+的分子内能量传递。 ZL-1在pH 9.0 PBS中展现出显著增强的ECL信号和较低的ECL电位，拓宽了工作环境的pH范围，对环境监测、生物和细胞免疫分析等 ...

A ratiometric fluorescence probe fabricated by encapsulating CsPbBr 3 in the three-dimensional hyperbranched Eu-MOF structure exhibits remarkable sensitivity, good linearity, and high selectivity for DMF detection.
