Embodiment Construction

[0027] The technical method of the present invention is illustrated below with specific examples, but protection scope of the present invention is not limited thereto:

[0028] The electron injection method of the metal organic framework MOF thin film of the present embodiment, comprises the following steps:

[0029] Step 1, configure the formic acid solution that the volume ratio of formic acid and water is 1:9;

[0030] Step 2, take 60 mg of zinc oxide powder and add it to 1 ml of formic acid solution, because the formic acid content is low, the reaction product of zinc oxide and formic acid is completely dissolved in the formic acid solution;

[0031] Step 3, take 0.5ml of ammonia water and add it to the solution formed in step 2, first a white precipitate insoluble matter is formed, and finally the white precipitate is completely dissolved to form a clear and transparent MOF solution;

[0032] Step 4, take the MOF solution and add it dropwise on the clean ITO glass, spin ...

Abstract

The invention provides an electron injection method of a metal-organic framework thin film. The electron injection method comprises the steps of (1) forming an MOF (Metal-Organic Framework) thin film on the surface of an electrode by use of an MOF precursor solution, and (2) injecting electrons into an electron transfer layer, wherein the preparation method of the MOF precursor solution in the step (1) comprises the steps of (11) dissolving an organic carboxylic acid into water or an alcohol solution to form an organic carboxylic acid solution, (12) adding a metal oxide powder to the organic carboxylic acid solution, and (13) adding an inorganic alkali solution to form a transparent mixed solution. The electron injection method of the MOF thin film has the advantages that the MOF precursor solution is simple to prepare without heating and pressurizing, the preparation process is good in stability, low in cost and suitable for large-scale industrial production, and the MOF thin film is high in electronic injection capability and extremely stable in air.

Description

technical field [0001] The invention relates to the field of organic semiconductor materials and electronic devices, in particular to an electron injection method of a metal-organic framework MOF thin film. Background technique [0002] The development of human beings is entering an energy-saving and low-carbon environment-friendly society, which will inevitably put forward new requirements for the electronic field that is closely related to human life. At present, traditional silicon-based electronic products still dominate all aspects of society, but this type of electronic product is expensive to process, consumes a lot of energy, is not easy to recycle, and seriously pollutes the environment. In recent years, the development momentum of organic semiconductor materials and electronic devices has been advancing rapidly, with great potential. The design functions of organic semiconductors are diversified, and can be applied to all fields where inorganic semiconductors can ...
