Abstract
The functionalized ligand (E)-4,4′-(1,4-bis(methylthio)but-2-ene-2,3-diyl)dibenzoic acid (H2LS) and four metal-organic frameworks, [M2(LH)3(DMSO)4]·xDMSO (6 and 7 for M = Tb3+, Eu3+ respectively; LH = (E)-4,4′-(ethene-1,2-diyl)dibenzoate) and [M2(LS)3(DMF)2(H2O)2] (8 and 9 for M = Eu3+, Tb3+) have been synthesized and characterized. All four MOFs adopt the anticipated connectivity, but the fold of interpenetration in each MOF crystal varies as a result of different solvent inclusion and ligand functionality. Compounds 6 and 7 contain a large amount of solvent molecules and tend to lose solvent in air. Compounds 8 and 9 are stable crystals without lattice solvent molecules in the crystals; the coordinating solvent molecules can be reversibly removed and replenished with the skeletons intact. All four MOFs show mainly the ligand-based luminescence, while 8 also displays metal-based luminescence.
