文摘

A 3D multifunctional lanthanide metal-organic framework (MOF), Er₄(TCPS)₃(H₂O)₆¡¤10DMF¡¤4H₂O (JUC-99) (H₄TCPS = tetrakis(4-carboxyphenyl)silane, DMF = N,N¡ä-dimethylformamide and JUC = Jilin University China) has been synthesized by self-assembly of Er(III) ions and rigid silicon-centered tetrahedral carboxylate ligands under solvothermal reactions. X-ray crystallography reveals that JUC-99 exhibits a unique trinodal (4,12)-connected topology, constructed from tetranuclear erbium clusters as 12-connected nodes and tetrahedral ligands TCPS as 4-connected nodes. To the best of our knowledge, JUC-99 is the first example of lanthanide MOFs with trinodal (4,12)-connected topology structure. In addition, the luminescent and magnetic properties of the compound are investigated.
