Selective and Sensitive Detection of Nitroaromatic Compounds by Fluorescent Europium Based Metal Organic Framework

摘要

Selective and rapid detection of nitroexplosives is one of the vital issues for human security as well as environmental safety. Fluorescence based detection methods have gained attention due to its high sensitivity, simplicity, short response time and ability to detect analytes both in solid and liquid phase. Herein, we report a fluorescent europium based Metal Organic Framework (MOF) for selective sensing of trace amounts of nitroaromatic compounds. Detection is done on basis of fluorescence quenching effect of different concentrations of nitrobenzene solutions. The experimental results showed that Eu-MOF extremely sensitive towards trace amount of nitrobenzene and show high selectivity among other non-nitroaromatic compounds as well.
