A 2D Zn(II) metal-organic framework constructed from 4,4′-(perfluoropropane-2,2-diyl)dibenzoic acid, synthesis, structure and photoluminescence

摘要

A Zn(II) metal-organic framework (MOF) [Zn₂(FPDB)₂(pyridine)₂] · 5H₂O (1) was synthesized solvothermally via reaction of Zn(ClO₄)₂ · 6H₂O and 4,4′-(perfluoropropane-2,2-diyl)dibenzoic acid (H₂FPDB). The X-ray single crystal diffraction analysis reveals that 1 crystallizes in monoclinic C2/c space group with a = 23.279(5) à , b = 7.837(5) à , c = 26.776(5) à , β = 106.7(6)° and Z = 4. In 1, two adjacent zinc ions are bridged to form a dinuclear paddle-wheel SBU, and four neighboring SBUs are linked by FPDB ligands to construct a chair-type grid. Distorted grids extended along a and b axes to complete a double-sheet 2D layer and these layers stack with van der Waal's interactions to build the final structure. Compound 1 shows strong luminescence at room temperature in the solid state, suggesting that 1 may be an excellent fluorescent material.View full textDownload full textKeywordsSolvothermally, Metal-organic framework, Trifluoromethyl, Carboxylate, Paddle-wheel, SBU, PhotoluminescenceRelated 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/10.1080/00958970802668844
