Embodiment 1

[0057] One of the micron and / or nano functional materials of coordination polymers of tetrathiafulvalene derivatives and metal ions - preparation of organic-inorganic composite semiconductor micron wires:

[0058] At a temperature of 10 degrees Celsius, first 4,4'(5')-bis-(4-pyridylvinyl)-tetrathiafulvalene (mass 8.2 mg) in dichloromethane solution (volume 5 ml) Add in the test tube, then slowly add lead perchlorate (10 mg in mass) in acetonitrile solution (5 ml in volume), because the specific gravity of acetonitrile is less than that of dichloromethane, the two solutions are separated in the test tube. Along with two kinds of solutions permeate and mix each other in the test tube, 4,4'(5')-bis-(4-pyridylvinyl)-tetrathiafulvalene and lead perchlorate react (molar ratio 1:1), A purple solid was obtained in the test tube after two weeks. SEM images (see figure 1 ) and TEM images (see figure 2 ) indicates that the purple solid is a micron wire, the diameter of the micron wir...

[0064] Micron and / or nano functional materials of coordination polymers of tetrathiafulvalene derivatives and metal ions 3- Preparation of organic-inorganic composite nanowires:

[0065] At a temperature of 5 degrees Celsius, the clean silicon wafer was immersed in the compound 4,4'(5')-bis-(4-pyridylvinyl)-tetrathiafulvalene and lead perchlorate at a molar ratio of 1:1. Acetone solution (concentration is about 1×10 -4 Mole per liter, volume is 10 milliliters), in the container that above-mentioned solution and silicon chip place are placed openly. Three days later, the acetone solvent in the container was completely volatilized, and the silicon wafer was taken out, and a large number of nanowires were formed on the surface of the silicon wafer as observed through a scanning electron microscope. SEM images (see Figure 8 ) and TEM images (see Figure 9 ) show that the maximum length of the nanowires reaches several hundreds of micrometers, and the diameter is 80 to 150 nano...

Abstract

The invention belongs to the field of materials, and relates to a method for synthesizing tetrathiafulvalene molecule-based micron and / or nano functional materials by a supermolecule self-assembly method. The method comprises the following steps: dissolving tetrathiafulvalene derivatives and inorganic metallic salts into solvents which have different specific gravities and can be mutually dissolved respectively, and making the solvent in which the tetrathiafulvalene derivatives are dissolved and the solvent in which the inorganic metallic salts are dissolved, which have different specific gravities, interpenetrate mutually and be mixed; or mixing the tetrathiafulvalene derivatives and the inorganic metallic salts, dissolving the mixture of the tetrathiafulvalene derivatives and the inorganic metallic salts into the same solvent, and volatilizing the solvent to obtain micron and / or nano functional materials of the tetrathiafulvalene derivatives and coordination polymers of metallic ions, composite micron and / or nano functional materials of cation free radicals of the tetrathiafulvalene derivatives and elementary metals, the micron and / or nano functional materials of the cation freeradicals of the tetrathiafulvalene derivatives, or the micron and / or nano functional materials of the elementary metals. The materials have the advantages of novel structure, uniform form, convenientpreparation and novel electrical and magnetic properties.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to synthesizing micron and / or nanometer functional materials of tetrathiafulvalene molecular bases by means of a supramolecular self-assembly method. Background technique [0002] Tetrathiafulvalene (TTF) and its derivatives are strong electron donors, which can be reversibly oxidized to stable positive monovalent (TTF +· ) cationic radical and positive divalent (TTF 2+ ) cations, so the research on tetrathiafulvalene and its derivatives in the field of functional materials such as organic conductors, organic magnets, and organic field effect tubes has been paid much attention. In recent years, the preparation of supramolecular micro- or nanoscale functional materials of functionalized tetrathiafulvalene and its derivatives through intermolecular non-covalent interactions has attracted the attention of scientists. The Kato research group in Japan, the Shinkai research group, t...
