3D LnIII-MOFs: displaying slow magnetic relaxation and highly sensitive luminescent sensing of alkylamines

Abstract

Six new 3D isomorphous lanthanide metal organic frameworks (Ln-MOFs), [Ln2(L)2(DMF)2(H2O)4]·H2O·DMF (Ln = Pr (1); Sm (2); Eu (3); Gd (4); Dy (5); Ho (6)); H3L = 5-(2-nitro-4-carboxylphenyl)isophthalic acid, have been solvothermally synthesized and characterized. Crystallographic studies revealed that these MOFs were isomorphous 3D frameworks in which the dinuclear units with double (µ-COO)2 bridges were interlinked by the L ligands. They represent the (3,6)-connected (42·6)(43·68·82·10·12) topology. The magnetic coupling through double carboxylate bridges is antiferromagnetic in Pr-MOF (1), Gd-MOF (4), Dy-MOF (5) and Ho-MOF (6). Furthermore, Dy-MOF (5) shows slow magnetic relaxation behaviors under zero dc field. The luminescent sensing experiments demonstrated that Eu-MOF (3) displayed highly selective, well-recyclable properties and low detection limit for sensing alkylamines in water system. The study of Ln-MOFs sensing for alkylamines is very scarce.
