The uranyl-organic framework based tripodal flexible zwitterion ligand 1,1',1''-[benzene-1,3,5-triyltris(methylene)] tris(pyridine-4-carboxylic acid) tribromine (H3LBr3), [(UO2)2(μ3-O)(μ2-OH)L]NO3·nH2O (n ≈ 5) (1) has been synthesized under hydrothermal condition and characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analysis, and UV-visible spectroscopy. Compound 1 contains a tetra-uranyl oxo-cluster, which displays a microporous 3D structure. The fluorescence measurement shows that 1 exhibits strong luminescence. Furthermore, 1 shows good photocatalytic activity for the degradation of methylene blue.
