Abstract: Based on the advantages of high sensitivity, simple operation and time-saving in the detection of metal ions by fluorescent analysis. We designed and synthesized a porous metal-organic framework crystal fluorescent probe with amino modification. The experimental results show that the compound is a two-fold interpenetrating structure of pcu framework, and the amino groups on the organic ligands are freely distributed in the channels. The compound has excellent thermal stability and water stability, and can be used as fluorescence enhanced probe to detect Ag⁺ in aqueous solutions, with the detection limit of 0.76 μmol/L.

Key words: metal-organic framework compound, , fluorescent probe, , Ag⁺, , amino-functionalization
