摘要

精心制作的纳米级荧光传感器，具有Eu3+功能化ZIF-8 (Eu3+@ZIF-8)，已成功合成利用精简有效的工艺。该荧光传感器巧妙地利用了Eu3+@ZIF-8中土霉素（OTC）和Eu3+离子之间的强大络合作用，通过精致的天线效应显着增强了Eu3+的特征荧光。这种增强有助于超灵敏的基于荧光的OTC传感。这一突破性的应用程序为OTC检测引入了一种新的范例，并对OTC检测的潜在机制进行了详尽的阐述。Eu3+@ZIF-8荧光传感器是OTC检测的先进工具，具有快速响应，无与伦比的选择性和灵敏度。它在环境样品（如湖水和自来水）中加标OTC检测中的应用已经证明了无可挑剔的性能，验证了其可靠性，并展示了一种具有巨大环境监测潜力的多功能平台技术。

Designed Eu3+-functionalized nano-MOF fluorescence sensor for rapid recognition of oxytetracycline

A meticulously crafted nanoscale fluorescence sensor, featuring Eu³⁺-functionalized ZIF-8 (Eu³⁺@ZIF-8), has been triumphantly synthesized utilizing a streamlined and effective process. This fluorescence sensor ingeniously harnesses the robust complexation between oxytetracycline (OTC) and Eu³⁺ ions within Eu³⁺@ZIF-8, markedly augmenting the characteristic fluorescence of Eu³⁺ via an exquisite antenna effect. This enhancement facilitates ultrasensitive fluorescence-based sensing of OTC. This groundbreaking application introduces a novel paradigm for OTC detection, accompanied by an exhaustive elaboration on the potential mechanism underlying OTC testing. The Eu³⁺@ZIF-8 fluorescence sensor stands as an exemplary advanced tool for OTC detection, evidenced by its remarkable attributes: swift response, unparalleled selectivity, and exquisite sensitivity. Its application in detecting spiked OTC in environmental samples, such as lake water and tap water, has demonstrated impeccable performance, validating its reliability and presenting a versatile platform technology with vast potential for environmental monitoring.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
