abstract The synthesis of pyrene-1,3,6,8-tetrayltetrakis(phosphonic acid) (H(8)ptp) and its use in the preparation of a new isotypical family of Metal-Organic Frameworks (MOF) using oxalic acid as secondary linker are reported. This new family, generally formulated as [Ln(2)(H(4)ptp)(ox)(H2O)(6)]center dot 5H(2)O [where Ln(3+)= Ce3+(1Ce), Pr3+(1Pr), Nd3+(1Nd), Sm3+(1Sm), Eu3+(1Eu), Gd3+(1Gd), Tb3+(1Tb) and Dy3+(1Dy)], were prepared under hydrothermal conditions and fully characterized using different techniques. The photoluminescence properties of1Euwere studied, showing emission lifetimes of 0.27 +/- 0.01 ms and 0.33 +/- 0.01 ms at 294 K and 12 K, respectively. This family of materials, based on a fully hydrolysed tetraphosphonate pyrene ligand, constitutes the first example of MOFs obtained using this highly fluorescent organic ligand.
