A three-dimensional microporous coordination polymer with fluorescent property

A microporous metal–organic coordination polymer formulated as [Cd2(btec)(H2O)2]·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 Å at the widest and 3 Å at the narrowest spacing considering the van der Waal radii of atoms in the framework running along the a-axis. Furthermore, compound 1 shows intense photoluminescent property at room temperature.
