Problems solved by technology

[0003] Traditional detection instruments have low sensitivity to the detection of carbon tetrachloride molecules and hexavalent heavy metal chromium ions
Carbon tetrachloride molecule is a colorless toxic liquid, which is very volatile, and it will be transformed into highly toxic phosgene or hydrogen chloride gas at high temperature, causing damage to the ozone layer and environmental pollution.
The hexavalent heavy metal chromium ion is a recognized water pollutant, generally represented by CrO 4 2- and Cr 2 o 7 2- Toxic heavy metal ions can also cause serious environmental pollution

Abstract

The invention relates to a cadmium metal organic framework complex. The cadmium metal organic framework complex is cooperatively formed by a flexible carboxylate ligand and a rigid imidazole ligand, the chemical formula is {Cd3(L)(phenDIB).6DMF}n, and the molecular formula is C90H96Cd3N10O25; the cadmium metal organic framework complex is a monoclinic space group C2 / c; and cell parameters are as follows: a / angstrom is 29.403(3), b / angstrom is 20.8279(19), c / angstrom is 16.9132(17), alpha is 90 degrees, beta is 111.067(2) degrees, V / angstrom is 6665.2(16), the density is 1.412mg / m<3>, the lightabsorption coefficient is 0.730mm<-1>, and the number of molecules in a single cell is 4. By utilizing the cadmium metal organic framework complex, the high-sensitivity selective detection of high-toxicity carbon tetrachloride molecules and hexavalent heavy metal chromium ions can be realized; and the cadmium metal organic framework complex has good application prospects.

Description

technical field [0001] The invention relates to the field of fluorescent materials, in particular to a cadmium metal organic framework complex. Background technique [0002] Metal-organic framework materials are a new type of porous crystal materials with structural advantages such as high specific surface area, high porosity, adjustable pore size, and functionalized pore surface, and have shown potential applications in many fields. value, such as gas storage and separation, heterogeneous catalysis, drug delivery, chemical detection, etc., among which the application of metal-organic framework materials as fluorescent sensors has received special attention. Compared with traditional detection instruments, fluorescent sensors made of metal-organic framework materials are easy to operate, cheap, and do not depend on electrical settings. Real-time online detection can be achieved, and they have high sensitivity and fast response. [0003] Traditional detection instruments hav...
