Abstract

A zinc-organic frame material with acetylacetone fluorescence response has a chemical formula of {[(CH3)2NH2][Zn(FDA)(BTZ)2]}n, wherein n is a natural number from 1 to positive infinity, FDA is acquired by deprotonation of 2,5-furandicarboxylic acid (H2FDA), and BTZ is acquired by deprotonation of 1H-benzotriazole (HBTZ). The zinc-organic frame material belongs to a trigonal system, has a space group of R3c and has cell parameters of a=27.0865(3) , b=27.0865(3) , c=11.2171(2) , alpha=90 degrees, beta=90 degrees and gamma=120 degrees. The zinc-organic frame material has good thermal stability;variable temperature XRD (X-ray diffraction) shows that crystal form of the zinc-organic frame material remains stable at 280 DEG C; the zinc-organic frame material has good fluorescence response to acetylacetone and may act as an acetylacetone fluorescence probe. The zinc-organic frame material has the advantages of good synthetic simplicity, good implementing convenience, high yield and the like; therefore, the zinc-organic frame material has great potential application value in the preparation of fluorescence probe solid-state devices.

Description

technical field [0001] The invention relates to a zinc-organic framework with acetylacetone fluorescence response and a preparation method, belonging to the technical field of porous crystal materials. Background technique [0002] Metal-organic frameworks (MOFs) are porous crystalline materials formed by coordination bonds between metal ions or clusters and organic ligands. Sensors, magnetic materials, gas adsorption and separation, catalysis, photoelectricity, etc. have attractive application potentials, and are rapidly developing into research hotspots in the interdisciplinary fields of energy, materials, and life sciences. See H.-C.Zhou et al., Chem.Soc . Rev. 2014, 43, 5415-5418. [0003] Fluorescent sensing materials based on metal-organic frameworks are considered to be one of the most promising detection methods and are widely used to identify harmful substances such as anions, cations, and small-molecule organics. The basic principle of this method is to detect su...
