摘要：

To　obtain　metal-organic　frameworks　(MOFs)　with　high　proton　conductivity,　three　new　MOFs,　[FeL0.5(NMP)2]n　(BUT-203),　[NiL0.5(DMA)2]n　(BUT-204),　and　[CoL0.5(DMA)(dpe)]•H2O　(BUT-205)　were　synthesized　through　the　solvothermal　reaction　between　a　sulfonic　acid　group　functionalized　ligand,　4,　8-disulfonaphthalene-2,　6-dicarboxylic　acid　(H4L)　and　Fe(NO3)3•9H2O,　Ni(CH3COO)2•4H2O,　or　CoCl2•6H2O,　respectively,　and　characterized　by　single-crystal　X-ray　diffraction　(SXRD),　thermogravimetric　analysis　(TGA),　infrared　spectroscopy　(FT-IR),　and　elemental　analysis　(EA).　BUT-203　and　BUT-204　are　isostructural　structures　with　one-dimensional　chain,　while　BUT-205　is　a　three-dimensional　framework　with　gwg　topology.　Impendence　tests　show　that　BUT-205　with　three-dimensional　structure　possesses　proton　conductivity　with　a　value　of　5.661×10-4　S/cm,　obviously　higher　than　that　of　one-dimensional　BUT-203　and　BUT-204.　This　fact　reveals　that　the　three-dimensional　structure　can　effectively　improve　the　proton　conductivity　of　MOFs.　©　2018,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
