Two Amino-Decorated Metal-Organic Frameworks for Highly Selective and Quantitatively Sensing of HgII and CrVI in Aqueous Solution

Two amino-decorated metal organic frameworks have been constructed, which are the rare examples of MOF-based fluorescent probes targeting environmentally relevant guest species, such as Hg (II) and Cr (VI) ions in aqueous solution, with high selectivity and sensitivity. The possible sensing mechanism is also discussed.
