Description
Summary:Framework-isomeric three-dimensional (3D) Zn-Ln heterometallic metal-organic frameworks, {[Ln 2 Zn(abtc) 2 (H 2 O) 4 ]·2H 2 O} ∞ {Ln = Sm(1), Tb(2)}, were synthesized using a convenient solvothermal reaction. They can serve as excellent sensors for the specific identification of benzaldehyde and NO 2 − through a fluorescence quenching process. Two 3d-4f heterometallic MOFs have been synthesized based on a tetracarboxylic ligand, and show good selective fluorescence sensing capabilities for nitrite and benzaldehyde.
