| titleOfInvention | A layered columnar zinc-based metal-organic framework material and preparation method |
| abstract | A layered columnar zinc-based metal-organic framework material and a preparation method, wherein the chemical formula of the framework material is: {[(CH 3 ) 2 NH 2 ] 0.5 [Zn(CBA)(TZT) 0.5 ·0.5DMA]} n , There is a zinc ion in the coordination environment in its basic structural unit, 1 deprotonated ligand CBA 2- , 0.5 deprotonated ligand TZT- and 0.5 free DMA molecules and 0.5 dimethylamine cations; adjacent The zinc ions form a two-dimensional layered planar structure in space through the dehydrogenation ligand CBA 2- ; the two-dimensional layered planar structure is further connected by the dehydrogenation ligand TZT-, thereby forming a three - dimensional layered columnar network in space structure. The material prepared by the invention is simple in synthesis, low in cost and high in stability, and can detect the existence of Cr(VI) ions in water through fluorescence quenching effect, and the detection limit for Cr 2 O 7 2- ion detection is 252 μmol· The detection limit of L ‑1 and CrO 4 2‑ ion detection is 56.7µmol·L ‑1 , so it has a huge potential application value in the detection of Cr(VI) ions in water. |
