Abstract:

A novel heterometallic-organic framework(HMOF), namely [ZnBa(1,3-BDC)2(DMA)2]n(1)(DMA=N,N-dimethylacetamide), was synthesized by means of solvothermal method from isophthalic acid(1,3-BDC) ligand and relevant metal salts as raw materials. The single-crystal X-ray diffraction analysis result demonstrates that compound 1 is a three-dimensional(3D) framework including heterometallic tetranuclear[Zn2Ba2(COO)8] clusters as building subunits, which could be simplified into an eight-connected body-centered cubic(bcu) topological net. At room temperature, compound 1 displays strong blue luminescence in solid state. Furthermore, the quantum yield and luminescent lifetime of compound 1 were also measured.

Key words: Barium, Isophthalic acid, Solvothermal, Luminescence property, Heterometallic-organic framework
