Metal-organic framework material based on TbII, and preparation method and application thereof

The invention relates to a metal-organic framework material based on TbII, and a preparation method and application thereof. The metal-organic framework material based on TbII belongs to a monoclinic system and a P2/c space group, and is a crystal with a two-dimensional network structure. The preparation method comprises the steps of adding Tb(NO3)2.6H2O, 4'-(1H-tetrazole-5)-biphenyl-3,5-dicarboxylic acid, ethyl alcohol and N,N'-dimethylformamide into a container, and stirring for 15 minutes at normal temperature; sealing the container, putting in a drying oven, and keeping for 36 hours under 358K. The material synthesized by the invention can be used as a sensor applied in detection of aluminum ions. The metal-organic framework material based on TbII can be used for sensitively and quickly detecting trace aluminum ions, the fluorescence intensity of the metal-organic framework material based on TbII can be gradually quenched along with the increase of aluminum ion concentration, and the metal-organic framewo
