A three-dimensional microporous coordination polymer with fluorescent property

Abstract A microporous metal–organic coordination polymer formulated as [Cd 2 (btec)(H 2 O) 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 A at the widest and 3 A 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.
