摘 要：Two 3D multifunctional lanthanide metal-organic frameworks（MOFs）, Pr（HTCPS）（H20）·2DMF·C2H2OH·5H2O（JUC-93） and Pr3（TCPS）2（NO3）（H2O）4（DMA）2.2DMA.C2H5OH.3H2O（JUC-94）[H4TCPS=tetrakis（4-carboxyphenyl）- silane, DMF=N,N＇-dimethylformamide, DMA=N,N＇-dimethylacetamide and JUC=Jilin University China] were synthe- sized by the self-assembly of a rigid silicon-centered tetrahedral carboxylate ligand H4TCPS and Pr（III） ions in different solvothermal reactions. X-Ray crystallography revealed that they exhibited a rare CaFE topology framework, constructed from the 4-connected tetrahedral TCPS unit with the 8-connected dinuclear praseodymium cluster unit and trinuclear praseodymium cluster unit, respectively. In addition, the luminescent and magnetic properties of the two compounds were investigated.
