A series of isomorphic lanthanide metal–organic frameworks (MOFs) Ln(TATAB)⋅(DMF) 4 (H 2 O)(MeOH) 0.5 (LnTATAB, Ln=Eu, Tb, Sm, Dy, Gd; H 3 TATAB=4,4′,4′′‐s‐triazine‐1,3,5‐triyltri‐ p ‐aminobenzoic acid) have been solvothermally synthesized and structurally characterized. Among these MOFs, TbTATAB exhibits good water stability and a high fluorescence quantum yield. Because mercury ions (Hg 2+ ) have a high affinity to nitrogen atoms, and the space between multiple nitrogen atoms from triazine and imino groups is suitable for interacting with Hg 2+ ions, TbTATAB shows highly selective and sensitive detection of Hg 2+ in aqueous solution with a detection limit of 4.4 n m . Furthermore, it was successfully applied to detect Hg 2+ ions in natural water samples.
