Two new isostructural 3D lanthanide-organic frameworks [H N(Me) ] [Ln (OH)(bpt) (H O) ] (DMF) ⋅(H O) (1-Ln; Ln=Sm and Eu) with a 1D channel (25 Å) have been successfully assembled from the rare trinuclear [Ln (OH)(COO) ] clusters and biphenyl-3,4',5-tricarboxylic acid (H bpt) and exhibit high stability towards water in the pH range 3-10. MOF 1-Eu is a promising luminescent probe for sensing Fe in aqueous solution and is also selective towards rhodamine B (RhB) with a superior adsorption capacity of 735 mg g , 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.
