specific Embodiment approach 1

[0014] Specific Embodiment 1: This embodiment is a method for preparing an organic-metal thin film, which is specifically carried out in the following steps:

[0015] 1. Mixed samples: Mix 4-amino-3,5-dimethylpyrazole, pyromellitic dianhydride and zinc nitrate uniformly in a reaction kettle, then add anhydrous N,N-dimethylformamide, Ultrasonic 10min~15min, obtain the reactor that mixed solution is housed; The mass ratio of described 4-amino-3,5-dimethylpyrazole and pyromellitic dianhydride is 1:(1.3~2); The mass ratio of described 4-amino-3,5-dimethylpyrazole and zinc nitrate is 1:(1.6~2); The volume ratio of amides is 1mol:(6mL~10mL);

[0016] 2. Hydrothermal method: put the reaction kettle with the mixed solution obtained in step 1 into a drying oven at 120°C for 4h-5h, cool down to room temperature with the furnace, open the reaction kettle and filter, and the obtained liquid is a supersaturated solution;

[0017] 3. Film preparation: apply the supersaturated solution obt...

specific Embodiment approach 2

[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that the mass ratio of 4-amino-3,5-dimethylpyrazole and pyromellitic dianhydride in Step 1 is 1:1.5. Others are the same as in the first embodiment.

specific Embodiment approach 3

Abstract

The invention relates to a preparation method of an organic-metal film. The invention aims at solving the technical problems that in the existing preparation method of the organic-metal film, most of synthetic substances are powder, a dense film is difficult to produce, the thickness of the film is relatively difficult to unify, the uniformity is poor, the steps are trivial, the production period of the film is relatively long and the production cost is relatively high. The preparation method of the organic-metal film, disclosed by the invention, is performed according to the following steps: 1) mixing samples; 2) performing a hydrothermal method; and 3) preparing the film. The preparation method disclosed by the invention has the advantages that the principle adopted by the invention is a hydrothermal synthesis method, high-temperature reaction is used to obtain a supersaturated solution, and then a spray coating or spin coating method is used to obtain the film; the film prepared by the method disclosed by the invention has uniform and controllable thickness and smooth surface, and by performing fluorescence and cyclic voltammetry tests on the film, the film is found to have good fluorescence performance; and furthermore, the organic-metal film has certain electrochemical performance, such as electrification color change or electrification illumination.

Description

technical field [0001] The invention relates to a preparation method of an organic-metal thin film. Background technique [0002] As a new type of organic-inorganic hybrid materials, metal-organic compounds have the advantages of high porosity, adjustable pore size and shape, and easy functionalization. Good application prospects. Metal-organic thin films are a class of multilayer materials with thickness ranging from nanometers to micrometers, physically or chemically attached to (functionalized) substrates. Ideally, such materials have a smooth surface and high homogeneity. A variety of novel methods have been used to prepare metal-organic compound thin-film materials. [0003] At present, there are many preparation methods for organic-metal thin films, including traditional solvothermal method, layer-by-layer growth method, sol-gel method, colloidal deposition method, and relatively novel microwave synthesis method, step-by-step liquid phase epitaxy growth method and e...
