Metal Organic Framework as a Ratiometric Fluorescence Sensor for Hypochlorite and Ascorbic Acid

Download Whitepaper
Metal organic frameworks (MOFs) are compounds containing metal ions and organic ligands arranged in a regular coordination network. They are useful in sensing applications since their porous structures enable the absorption of analytes of a particular size. Moreover, it is possible to employ a fluorescent MOF as a sensor if its photoluminescence properties change in the presence of the analyte. This idea has been previously exploited for ClO– detection, but always based on a single emission intensity. In this study, Zeng et al. propose a ratiometric fluorescence sensor to improve sensitivity and robustness.
