Embodiment 1

[0015] Embodiment 1 (C 19 h 19 AgN 2 o 3 S)

[0016] The ratio of benzenesulfonic acid, sodium hydroxide, DPP (1,3-di(pyridin-4-yl) propane) and silver nitrate is 0.1~3.5:0.1~3.5:0.1~3.5:0.1~3.5; organic solvent methanol and The ratio of water is 1:1~3; the reaction time is 0.5~72 hours. White lumpy crystals were precipitated by filtration.

[0017] Characterization of the above metal-silver coordination polymers containing mixed ligands

[0018] The crystal X-ray diffraction data were determined by Burkcer Smart CCD single crystal diffractometer. MoKa radiation (λ=0.71073Å ), graphite monochromator, data collected in ω-scan mode, and Lp factor correction and empirical absorption correction were performed. First use the direct method to determine the position of metal atoms and some other non-hydrogen atoms, then use the difference function method and the least square method to find the coordinates of all other non-hydrogen atoms, and use the theoretical hydrogenation m...

Abstract

The invention relates to the synthesis of coordination polymers, and specifically discloses a metal silver coordination polymer containing mixed ligands and a preparation method thereof. A metal silver coordination polymer containing mixed ligands, the chemical formula is: [Ag(BS)(BPP) 2 ] n . Wherein BS is benzenesulfonate, and DPP is 1,3-bis(4-pyridyl)propane. The specific method is as follows: BS ligand, DPP ligand and metal salt are mixed and dissolved in a mixed solution of water and methanol in a certain proportion of substances, a certain amount of sodium hydroxide is added, and crystallized at room temperature for 3 days, and a block is precipitated. crystals. The preparation method of the coordination polymer has the advantages of simple process, no pollution and high crystallinity. The metal-silver coordination polymer containing mixed ligands has very good potential application prospects in the field of light emission.

Description

technical field [0001] The invention belongs to the field of metal-organic coordination polymers and fluorescent materials, and relates to the preparation and application of a metal-silver coordination polymer containing mixed ligands. Background technique [0002] Coordination polymers refer to complexes with highly regular wireless network structures formed by the self-assembly of organic ligands and metal ions through coordination bonds, hydrogen bonds, and covalent bonds. As a new type of functional material, metal coordination polymers have potential applications in gas catalysis, gas absorption or storage, sensing, drug delivery, and fluorescence. [0003] In recent years, aromatic silver sulfonate complexes formed by the self-assembly of metal silver ions and organic sulfonic acid molecular building blocks have attracted the attention of chemists at home and abroad. Mainly because: (1) silver ions have a wide range of coordination numbers and rich coordination polyhe...
