Embodiment 1

[0029] This example relates to a method for preparing 4,4',4",4"'-(perylene-1,3,6,8-tetraphenyl)tetraphenylcarboxylic acid, which specifically includes the following steps: (4-( Methoxycarbonyl)phenyl)boronic acid (1.040g, 5.80mmol), 1,3,6,8-tetrabromoperylene (0.500g, 0.97mmol), tetrakis(triphenylphosphine)palladium(0) (0.030g 0.026 mmol) and anhydrous tripotassium phosphate (1.100 g, 5.30 mmol) were charged (in the glove box) into a 20 mL microwave vial and capped. The mixture was stirred at 130°C in an oil bath under argon for 72 hours. The reaction mixture was evaporated to dryness, and the solid residue was washed with water to remove inorganic salts. The insolubles were extracted with chloroform (3 times 50 mL), the extract was dried over magnesium sulfate, and the solvent volume was reduced under vacuum. The residue was boiled in tetrahydrofuran for 2 hours and filtered; the resulting filtrate contained mainly impurities. This procedure gave 0.58 g of 1,3,6,8-tetraki...

Embodiment 2

[0031] This embodiment relates to a preparation method for preparing fluorescent cadmium-MOFs complexes, which specifically includes the following steps:

[0032] Accurately weigh the Cd(NO 3 ) 2 4H 2 O (50mg, 0.2mmol), Ligand H 4 L (5mg, 0.01mmol) was put into a 10ml glass bottle, screwed the bottle cap tightly, and then added 2ml of a mixed solution of N,N-dimethylacetamide, 1,4-dioxane and water (volume ratio= 5:2:1), after ultrasonication for 10min, put it into an electric constant temperature blast drying oven, raise the temperature to 100°C for 300min, and keep it for 4320min, then -1 Slowly cool the reaction system to room temperature. Bright yellow blocky crystals were obtained. Elemental analysis test value (theoretical value) / %: C: 54.98%; H: 4.32%; N: 1.23%. Elemental analysis actual value / %: C: 54.77%; H: 4.18%; N: 1.12%.

[0033] Under room temperature conditions, the cadmium-MOFs complex prepared in this example was characterized by powder X-ray diffraction...

Abstract

The invention discloses preparation for a cadmium-MOFs complex with the fluorescence property. According to the preparation for the cadmium-MOFs complex, the molecular formula of the cadmium-MOFs complex is {[Cd2(L)(H2O)].DMA.Diox.2H2O}n, the structure of the complex belongs to P-1 space groups, basic structural units of crystals is obtained by carrying out symmetry operation on asymmetric units,the symmetry operation code is <1>1-X, 2-Y, 1-Z; <2>1+X, +Y, 1+Z; <3>1-X, 3-Y,-Z; <4>2-X, 3-Y, 1-Z, <5>-1+X, +Y, -1+Z; <6>2-X, 3-Y,-Z, each asymmetric unit is provided with a coordinate ligand, two Cd<2+> ions and a coordinate H2O molecule, the Cd<2+> ions with two coordination modes exist in the complex, Cd1 adopts a seven-coordination mode, six oxygen atoms are respectively from four different perylene derivative ligands, the other oxygen atom is from the coordinate H2O molecule, Cd2 adopts a six-coordination mode, four oxygen atoms are respectively from four different perylene derivative ligands, and the other two oxygen atoms are from the coordinate H2O molecule. The preparation for the cadmium-MOFs complex has the advantage that controllable preparation of the fluorescent complex canbe realized.

Description

technical field [0001] The invention belongs to the technical field of new materials, and specifically discloses a cadmium-MOFs complex with fluorescent properties. Background technique [0002] Metal-organic framework materials are being studied by more and more people because of their unique advantages-porosity, easy-to-adjust and modify pore size, and ultra-high specific surface area. They are used in many aspects such as fluorescence recognition, gas separation, and electrocatalysis Both have great applications. [0003] With the increasingly serious environmental pollution, the treatment of sewage and the reduction of excessive heavy metals in sewage have become problems to be solved urgently. However, traditional detection methods have limited their wide application in industry due to their shortcomings such as low sensitivity and high cost. Contents of the invention [0004] The object of the present invention is to provide a cadmium-MOFs complex with fluorescent ...
