A three-dimensional microporous coordination polymer with fluorescent property

A microporous metal-organic coordination polymer formulated as [Cd-2(btec)(H2O)(2)]center dot 0.8DMF (1), where btec = 1,2,4,5-benzenetetracarboxylate and DMF = N,N-dimethylformamide, has been isolated under solvothermal condition and characterized by elemental analyses, IR, thermal stability analysis, fluorescent spectrum, and single-crystal X-ray diffraction analysis. The framework in 1 possesses a three-dimensional architecture with ordered one-dimensional rhombus channels, the dimensions of channels are approximately 10 angstrom at the widest and 3 angstrom at the narrowest spacing considering the van der Waal radii of atoms in the framework running along the a-axis. Furthermore, compound I shows intense photoluminescent property at room temperature. Q 2008 Published by Elsevier B.V.
