Luminescent two-dimensional CdII coordination polymer for selective sensing Fe3Â + and 2,4,6-trinitrophenol with high sensitivity in water

A new 2D double layer coordination polymer {[Cd(PYIA)(H2O)]·H2O}n (SUF-1) was synthesized based on a rigid N-containing ligand, which exhibited excellent selectivity and highly sensitivity detective of Fe3 + and 2,4,6-trinitrophenol with a fluorescence quenching mechanism in water.110
