A Luminescent Metal-Organic Framework with LON Topology for Highly Effective Fluorescence Sensing of Fe3+ and TNP
A luminescent Ag-based metal-organic framework(compound 1) has been synthesized and its structure has been characterized. Compound 1 was fabricated using the Ag+ and bbimb2− ligands and manifestes a rare LON topology. Compound 1 is selective not only in detecting traces of Fe3+ and 2,4,6-trinitrophenol(TNP) via luminescence quenching, but also demonstrates high selectivity in the presence of other competitors. Compound 1’s K sv values towards Fe3+ can reach as high as 9.3×l03 L/mol, which is higher than those of several other MOF materials. It is also a recyclable luminous sensor with the potential to be utilized for detecting TNP. Hence, based on its characteristics, compound 1 can be regarded as a prospective luminescence sensor for detecting Fe3+ and TNP.
