Functional Construction of a Novel Lanthanide MOF for Efficient Ratio Luminescence Detection of Ethanol Vapor

Advanced Optical Materials, Journal Year: 2024, Volume and Issue: 12(22)

Published: May 3, 2024

Abstract It is necessary to develop excellent sensors for volatile organic compounds (VOCs) detection from the perspective of environmental protection and human health. Luminescent lanthanide metal‐organic frameworks (MOFs) have many advantages such as porosity, luminescence, structural controllability, making them very suitable luminescent sensing materials. Based on a functional oriented strategy, novel Ln‐MOFs are successfully constructed their structure properties characterized in detail. A series vapor luminescence tests shown that Eu/Tb doped L1‐Eu 0.1 /Tb 0.9 not only exhibits high selectivity alcohols, especially ethanol vapor, but also has sensitivity extremely low limit (9.76 mg L −1 ). To knowledge, there no reports ratio based those with performance. Crystal determination demonstrates binds framework through multiple hydrogen bonding interactions, altering energy transfer efficiency between Tb 3+ Eu achieve detection. In addition, good repeatability, prepared thin film material portability processability. This work can provide some experience development VOCs materials better

A Multimode Optical Sensor for Selective and Sensitive Detection of Harmful Heavy Metal Cr(VI) in Fresh Water and Sea Water

Analytical Chemistry, Journal Year: 2024, Volume and Issue: 96(21), P. 8705 - 8712

Published: May 8, 2024

Water pollution originating from heavy metals has shown great impacts on the ecological environment and human health due to their extremely low biodegradability. Hexavalent chromium Cr(VI), as one harmful metal with strong oxidation, high biological permeability, carcinogenicity, is becoming an increasingly serious threat health. Therefore, conveniently but accurately, monitoring Cr(VI) level in water maintain its normal ensuring stability of ecosystem become very valuable. However, most these sensors reported are turn-off type single-emission sensors. In this work, a ratiometric fluorescence/colorimetry/smartphone triple-mode turn-on optical sensor for was developed based multifunctional metal–organic framework platform. The detection limits three mutual verification modes were only 1.28, 4.89, 68.4 nM, respectively. Additionally, color changes system under sunlight can also be observed directly by naked eye. accuracy practicability multimode further proved actual seawater samples, recovery rate ranged 97.308 104.041%.
