| Abstract: A layered coordination polymer[Cd(QDA)]n (1) with distorted Cd2+ octahedron extended by three-connected 2,3-quinoline dicarboxylate linkers was hydrothermally synthesized, exhibiting intense blue fluorescence and highly thermal and chemical stability. More interestingly, the complex dispersed in ethanol can quickly probe the trace amounts of 2,4,6-trinitrophenol (Ksv=6.61×104 L·mol-1, LOD=0.83 μmol·L-1) and Fe3+ (Ksv=1.74×104 L·mol-1, LOD=2.70 μmol·L-1) through fluorescence quenching with high quenching constants (Ksv) and low limits of detection (LOD). |
