Embodiment 1

[0033] 0.29g of zinc nitrate hexahydrate and 0.13g of terephthalic acid were dissolved in 10mL of DMF, and the solution was reacted in a reactor for 21 hours at a temperature of 120°C. The resulting solid was washed three times with DMF and then dried. Take 10mg of solid powder for XRD characterization, such as figure 1 As shown, the structure is MOF-5 (pore size 1-2nm). Take 20mg MOF-5 powder, soak in 5mL of Sc 3 NC 80 in toluene solution (containing 2mgSc 3 NC 80 ). During immersion, red Sc is visible to the naked eye 3 NC 80 The color of the toluene solution gradually becomes lighter until it disappears. At the same time, the color of MOF-5 gradually changes from white to red, indicating that Sc 3 NC 80 into the pores of the MOF. After 3 days, the solid was taken out, washed with toluene and dried for characterization.

Embodiment 2

[0036]5.14g of aluminum nitrate nonahydrate and 1.66g of terephthalic acid were dissolved in 28.8mL of water, and the solution was reacted in a reactor for three days at a temperature of 220 degrees. The obtained solid was washed with water three times and then dried. Take 10mg of solid powder for XRD characterization, such as image 3 As shown, the structure is MIL-53 (pore size 2.6-8.5nm). Take 20mg MIL-53 powder and divide it into two parts, one part soaked in 5mLSc 3 NC 80 Toluene solution (containing 2mgSc 3 NC 80 ), one part soaked in 5mLY 2 C 79 N in toluene solution (containing 2mgY 2 C 79 N). During immersion, red Sc is visible to the naked eye 3 NC 80 and Y 2 C 79 The color of the toluene solution of N gradually becomes lighter until it disappears, and the color of MOF-5 gradually changes from white to red, indicating that Sc 3 NC 80 and Y 2 C 79 N enters the channels of MOF. After 3 days, the solid was taken out, washed with toluene and dried for ch...

Embodiment 3

[0039] 5.14g of aluminum nitrate nonahydrate and 1.66g of terephthalic acid were dissolved in 28.8mL of water, and the solution was reacted in a reactor for three days at a temperature of 220 degrees. The obtained solid was washed with water three times and then dried. Soak 10mg of MIL-53 (pore size 2.6-8.5nm) powder in 5mLY 2 C 79 N in toluene solution (containing 2mgY 2 C 79 N). After 3 days, the solid was taken out, washed with toluene and dried for characterization.

Y 2 C 79 The ESR spectrum of N in solution originally has three groups of peaks (such as Image 6 A). Y 2 C 79 In the complex of N and MIL-53, Y can be clearly seen 2 C 79 Two sets of split peaks for N (see Image 6 B two groups of signals on the right, Y 2 C 79 Another set of peaks for N is masked by the signal of MIL-53)....

Abstract

The invention provides a metal-organic framework compound-metal fullerene compound and a preparation method thereof. The method is characterized in that a metal-organic framework compound material is immersed into a metal fullerene organic solution to obtain a mixing system of the metal-organic framework compound-metal fullerene compound. The metal-organic framework compound material takes organic carboxylic acid as an organic ligand and takes transition metal as a node for constitution; the metal fullerene is selected from at least one of the followings: M@C2n, M2@C2n, M3N@C2n, M3CN@C2n, M2C2@C2n, M3C2@C2n,and M2@C79N, wherein M is Sc, Y and lanthanide metals, and n is 30-50. The metal-organic framework compound is used for absorbing metal fullerene, and a metal fullerene structure with monodispersity under a solid state.

Description

technical field [0001] The invention belongs to the field of metal fullerene composite materials, and in particular relates to a metal organic framework compound-metal fullerene composite and a preparation method thereof. Background technique [0002] At present, embedded metallofullerene molecules have attracted much attention due to their unique nested structure and excellent physical and chemical properties, and have become important functional materials in the fields of physics, chemistry, materials and life sciences. Metallofullerenes and their derivatives have a wide range of applications in magnetic materials, quantum information processing, solar receptors, MRI contrast agents, antitumor drugs, and photodynamic therapy drugs. [0003] The application of metallofullerenes still faces some problems. For example, bulk metallofullerene materials with ordered structures have potential applications in quantum information storage, but their single crystals are difficult to ...
