Embodiment 1

[0042] First the glass substrate is cleaned. That is, the glass substrate was ultrasonically washed for half an hour in a mixed solution of acetone, isopropanol and water with a volume ratio of 1:1:1, and then ultrasonically washed with deionized water for 10 minutes. Then rinse with ethanol and blow dry with nitrogen. Put it in the prepared piranha solution (volume ratio of sulfuric acid:hydrogen peroxide is 7:3), heat to 100°C, cook for about half an hour, cool down, then pour out the piranha solution, (Note: Piranha The solution is very corrosive, and corresponding protection measures must be taken), ultrasonically washed twice with deionized water, and stored in deionized water.

[0043] Prepare 0.01-1mol / L copper acetate solution and 0.01-1mol / L methanol solution of HHTP organic ligand, fix the above glass substrate on a substrate, first take 3mL copper acetate solution, spray for about 20 seconds, then Spray with 4 mL of ethanol and dry with nitrogen. Then take 6 mL o...

Embodiment 2

[0047] First the sapphire substrate is cleaned. That is, the sapphire substrate was ultrasonically washed for half an hour in a mixed solution of acetone, isopropanol and water with a volume ratio of 1:1:1, and then ultrasonically washed with deionized water for 10 minutes. Then rinse with ethanol and blow dry with nitrogen. Configure 0.01mol / L ethanol solution of copper nitrate and 0.1mol / L ethanol solution of 2,3,6,7,10,11-hexaaminotriphenylene (HATP) organic ligand, and fix the above substrate on a substrate First, take 3mL of copper acetate ethanol solution, spray for about 20 seconds, then spray with 4mL of ethanol, and blow dry with nitrogen. Immediately after that, 6 mL of ethanol solution of BHT organic ligand was sprayed for about 40 seconds, followed by spray washing with 4 mL of ethanol, and blown dry with nitrogen. This is a cycle, the thickness of the grown film is one layer, and this step is repeated to grow a film with a specific thickness.

Embodiment 3

[0049] Firstly, the Si substrate is cleaned. That is, the substrate was ultrasonically washed for half an hour in a mixed solution of acetone, isopropanol and water with a volume ratio of 1:1:1, and then ultrasonically washed with deionized water for 10 minutes. Then rinse with ethanol and blow dry with nitrogen. Configure 0.01mol / L ethanol solution of nickel nitrate and 0.1mol / L ethanol solution of 2,3,6,7,10,11-hexaaminotriphenylene (HATP) organic ligand, and fix the above substrate on a substrate First, take 3mL of nickel nitrate ethanol solution, spray for about 20 seconds, then spray with 4mL of ethanol, and blow dry with nitrogen. Immediately after that, 6 mL of ethanol solution of BHT organic ligand was sprayed for about 40 seconds, followed by spray washing with 4 mL of ethanol, and blown dry with nitrogen. This is a cycle, the thickness of the grown film is one layer, and this step is repeated to grow a film with a specific thickness.

Abstract

The invention discloses an electronically conductive metal organic frame film and a preparation method and an application thereof. The EC-MOFs film has high quality and controllable thickness, the disadvantage that an EC-MOFs nano porous film whose thickness and quality are not controllable layer and layer on the nanometer scale in the prior art is solved, and the EC MOFs film obtained in the invention applied to a room temperature chemical resistance type gas sensor has high selectivity and fast response.

Description

technical field [0001] The invention belongs to the technical field of thin films and their preparation, and in particular relates to an electronically conductive metal organic framework thin film used for thin film electrical devices such as supercapacitors, lithium batteries, and gas sensors, as well as its preparation method and application. Background technique [0002] Electronic Conductive Metal–Organic Frameworks (EC-MOFs) materials are an emerging class of conductive porous crystalline materials formed by self-assembly of metal ions or metal ion clusters and organic ligands through coordination bonds. Different from conventional organic semiconductors and inorganic semiconductors, EC-MOFs are a new class of crystalline materials that combine porosity, selectivity and semiconductor properties. The reported conductivity of EC-MOFs has reached 50S cm -1 , exceeding conductive carbon materials widely used in electrical devices, including activated carbon. Among them, Y...
