Synthesis, characterization and luminescent property of a novel zinc(II) 1,2,3,4-tetra(4-pyridyl)thiophene metal-organic framework

摘要

A novel metal-organic framework (MOF) [Zn(TPT)(MPDCO)(H2O)·H2O]n (TPT= 1,2,3,4-tetra (4-pyri-dyl)thiophene, MPDCO = 6-methylpyridine-2,4-dicarboxylic acid N-oxide) (1) was obtained via hydro-thermal 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 1 exhibits efficient blue luminescence at room temperature, and the framework is stable below 235 °C
