title: The Uncommon Channel-Based Ln-MOFs for Highly Selective Fe3+Detection and Superior Rhodamine B Adsorption.
abstract: Two new isostructural 3D lanthanide-organic frameworks [H2N(Me)2] [Ln3(OH)(bpt)3(H2O)3] (DMF)2⋅(H2O)4(1-Ln; Ln=Sm and Eu) with a 1D channel (25 Å) have been successfully assembled from the rare trinuclear [Ln3(OH)(COO)9] clusters and biphenyl-3,4',5-tricarboxylic acid (H3bpt) and exhibit high stability towards water in the pH range 3-10. MOF 1-Eu is a promising luminescent probe for sensing Fe3+in aqueous solution and is also selective towards rhodamine B (RhB) with a superior adsorption capacity of 735 mg g-1, which is the highest among the reported Ln-MOFs for RhB removal so far. Periodic DFT calculations further confirmed the selective adsorption of rhodamine B over other dyes.
