Multifunctional Three-Dimensional Europium Metal–Organic Framework for Luminescence Sensing of Benzaldehyde and Cu2+ and Selective Capture of Dye Molecules

A multifunctional three-dimensional lanthanide metal–organic framework has been rationally constructed. Highly selective sensing of benzaldehyde and Cu2+ ions makes it a potential bifunctional sensor. Also, it could serve as a good candidate material for the removal of dyes from effluents based on the size exclusion.
