The synthesis of pyrene‐1,3,6,8‐tetrayltetrakis(phosphonic acid) (H8ptp) 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 [Ln2(H4ptp)(ox)(H2O)6]·5H2O [where Ln3+ = 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 of 1Eu were 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.

Te四膦酸盐基金属有机骨架:结构和光致发光

据报道of-1,3,6,8-四烷基四膦酸(H 8 ptp)的合成及其在使用草酸作为二级连接子的金属-有机骨架(MOF)同型新家族的制备中的用途。这种新的家族,通常配制成[LN 2(H 4 PTP)(OX)(H 2 O)6 ] · 5H 2 -O [其中Ln 3+ =铈3+1CE),PR 3+1PR),钕3+1Nd),Sm 3+1Sm),Eu 3+1Eu),Gd 3+1Gd),Tb 3+1Tb)和Dy 3+1Dy)]是在水热条件下制备的,并使用不同的技术对其进行了全面表征。研究了1Eu的光致发光特性,在294 K和12 K下的发射寿命分别为0.27±0.01 ms和0.33±0.01 ms。基于完全水解的四膦酸酯pyr配体的材料族构成了使用这种高度荧光的有机配体获得的MOF的第一个例子。
