Abstract

The invention discloses a luminous porous coordination polymer as well as a preparation method and application thereof. The polymer disclosed by the invention has the chemical formula of [Cd2(tba)3Cl], wherein tba-1 refers to anion of a ligand 4-(1,2,4-1H-triazole) benzoic acid. The crystal structure of the polymer refers to an orthorhombic system, namely, a Pnma space group and has a one-dimensional channel formed by bridging the tba-1 main ligand and chloride ion auxiliary ligand with cadmium ions, and the hole ratio of the three-dimensional frame structure is 37.5 percent. The polymer is prepared by adopting a solvothermal method. The polymer can be used for a fluorescence probe for identifying different aromatic molecules and particularly serves as a molecular fluorescent probe for identifying N,N-dimethylaniline from the aromatic molecules. The preparation process disclosed by the invention is simple and easy to implement, the crystal purity and yield of the product are high, the detection method is simple, the selectivity is high, and the polymer has good prospects in the aspect of serving as a fluorescence probe and a solid luminous material.

Description

technical field [0001] The invention relates to a porous coordination polymer material, especially a light-emitting porous coordination polymer and its preparation method and application. Background technique [0002] Porous coordination polymer is a new type of porous material developed in recent years. Compared with traditional porous materials such as molecular sieves and activated carbon, it has the advantages of low density, large specific surface area, strong chemical modifiability, and structural flexibility. It can be widely used Used in storage, separation, heterogeneous catalysis of gas and liquid, etc. [0003] In recent years, porous coordination polymer materials with luminescent properties have attracted great research interest, because this type of compound combines luminescent properties and porous adsorption properties, and uses the coordination polymer skeleton as the "main body" , using its internal pores to adsorb guest molecules with specific properties...
