Blue fluorescence emission property of a metal-organic coordination polymer with one-dimensional channels

Abstract

A metal-organic coordination polymer formulated as (H3O) 2[Zn(BTEC)] (1), where BTEC = 1,2,4,5-benzenetetracarboxylate, was synthesized by solvothermal reaction and characterized by elemental analyses, thermal stability analysis, fluorescence and IR spectroscopy, as well, as single-crystal X-ray diffraction analysis. Compound 1 is a three-dimensional network containing one-dimensional rhombic channels, the sizes of the windows are approximately 8 Â at the widest and 4.5 Â at the narrowest spacing (excluding the van der Waals radius of atoms in the framework) running along the c axis. The study of the physical properties of 1 demonstrates that it exhibits intense blue fluorescence emission in solid state at room temperature. © 2009 WILEY-VCH Verlag GmbH & Co. KGaA.
