Unique tailored porous frameworks incorporating a lanthanide metal center have been designed to function as chemical detectors. A flexible multidentate ligand, mucic acid, is used to differentiate between several anions, thus creating an organic framework (see figure) that is ideally suited for applications in gas separation, sensors, and chemical switches.
