A water-stable La-based coordination polymer for highly fluorescent detection of Fe3Â + ion and nitrobenzene vapor

A water-stable La-based coordination polymer has been prepared by employing a triphenylamine moiety functionalized luminescent ligand. This compound not only possesses a novel (3,12)-connected framework structure, but also could behave as a fluorescent probe for selective detection of Fe3 + ion with good stability and recyclability in water. Additionally, this compound also shows a fast response to trace amount of nitrobenzene vapor via a fluorescence quenching.350
