以2，2 ′-联吡啶-3，3 ′-二甲酸（H2 BPDC）和草酸（H2OX）为原料，采用混合配体法合成了两种银-镧系（III）杂金属有机骨架（HMOFs）{[Ln 3Ag 3（BPDC）5（OX）（H2O）7]·7 H2O}n（Ln = Tb（1），Gd（2））.单晶X-射线衍射研究表明，该化合物具有（3，4，5）-连接的新拓扑结构{3·42·5·62}{3·43·52·63·7}{3·5·62·9·10}{42·5·63}{42·5}{42·6}{43·5·62}{43·63}{43·64·82·10}。荧光研究表明，HMOF 1具有Tb 3+离子的特征发射，可用于有机小分子污染物和金属离子的传感。此外，它还可以区分戊醇的异构体以及定量区分致癌但用于染发的苯胺。
Two silver(I)–lanthanide(III) heterometallic-organic frameworks (HMOFs) {[Ln3Ag3(BPDC)5(OX)(H2O)7]·7H2O}n (Ln = Tb (1), Gd (2)) have been synthesized via a mixed ligand approach using 2,2′-bipyridine-3,3′-dicarboxylic acid (H2BPDC) and oxalic acid (H2OX) under hydrothermal conditions. Single crystal X-ray diffraction studies showed a (3,4,5)-connected new topology of {3·42·5·62}{3·43·52·63·7}{3·5·62·9·10}{42·5·63}{42·5}{42·6}{43·5·62}{43·63}{43·64·82·10}. Luminescence studies showed that the characteristic emissions of Tb3+ ions are observed in HMOF 1 which can be capable of sensing organic small-molecule pollutants and metal ions. In addition, it can also discriminate the isomers of pentanol as well as quantitatively distinguish benzendiamines which are carcinogenic but used for hair coloring.
