Magnetic core–shell microspheres were developed to extract rare earth elements (REEs) from aqueous and brine solutions with up to 99.99% removal efficiency. The shell, composed of a thermally and chemically stable functionalized metal–organic framework (MOF), is grown over a synthesized Fe3O4 magnetic core (magnetite@MOF).

A rosebengal-modified nanoporous structure was designed and constructed. This composite structure consisted of an organic sensitizer based on rosebengal and a supporting host of rare earth metal-organic-framework (MOF). It was identified by means of its x-ray diffraction (XRD) pattern, Infrared (IR) spectra, thermal stability and photophysical measurements. Its absorption was increased by 2,4,6-trinitrophenol. Its rosebengal emission was proportionally increased. But its rare earth emission was well-preserved, offering ratiometric signals. These two sensing modes exhibited linear response and good selectivity with a limit of detection (LOD) of 1.9 μM. Its sensing nature was confirmed as the combination of increased rosebengal emission and rare earth emission quenching effect triggered electron-deficient molecules. This nanoporous structure was superior to traditional ones owing to its double sensing modes.

Organic Framework

The title compound, [Tb(C9H3O6)(C4H9NO)2], shows a rare-earth three-dimensional metal-organic framework structure. In this complex of an eight-coordinated Tb3+ion, the asymmetric unit contains one benzene-1,3,5-tricarboxylic ligand and two coordinated dimethylacetamide molecules. Each Tb3+ion is coordinated by six O atoms from four carboxylate groups of the benzene-1,3,5-tricarboxylic ligands and two O atoms from two terminal dimethylacetamide molecules.
