摘　　要：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 Fe^(3+)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 Fe^(3+)can reach as high as 9.3×l0^(3) 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 Fe^(3+)and TNP.
