摘要
A novel metal-organic framework (MOF) [Zn(TPT)(MPDCO)(H2O)center dot H2O](n) (TPT = 1,2,3,4-tetra (4-pyridyl)thiophene, MPDCO = 6-methylpyridine-2,4-dicarboxylic acid N-oxide) (1) was obtained via hydrothermal synthesis and characterized by the elemental analysis, IR spectroscopy, TG analysis, luminescent spectroscopy and single-crystal X-ray diffraction analysis. Single-crystal structural analysis reveals that a one-dimensional (1-D) ladderlike MOF is constructed through the mixed ligands, and it is further connected by the intermolecular hydrogen bonds to form a 3-D supramolecular network. Complex I exhibits efficient blue luminescence at room temperature, and the framework is stable below 235 degrees C. (C) 2009 Elsevier B.V. All rights reserved.
