A 3-D metal-organic framework constructed with cobalt(II), 1,3-di(4-pyridyl)propane (bpp) and 3,5-dinitrobenzoate (DNBA) with methyl-3,5-dinitrobenzoate (MDNBA) by in-situ synthesis as a guest

摘要

A new 3-D cobalt(II) mixed ligand, metal-organic framework {[Co₂(bpp)₂(DNBA)₄H₂O]  · MDNBA} (1), (bpp  = 1,3-di(4-pyridyl)propane, DNBA  = 3,5-dinitrobenzoate and MDNBA  = methyl-3,5-dinitrobenzoate) was synthesized in aqueous-methanol medium. X-ray structural analysis of 1 revealed that the dinuclear cobalt clusters interlinked by two μ-carboxylates and a μ ₂ water molecule, acting as a node, are connected to four other clusters through bridging bpp to generate an extended neutral 3-D network. MDNBA was in-situ synthesized and encapsulated in the framework as a guest molecule. Moreover, the fluorescence spectrum shows 1 exhibits blue fluorescent emission in the solid state at room temperature.View full textDownload full textKeywords In-situ , Hydrothermal synthesis, Metal-organic framework, Crystal structureRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00958970701615854
