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 free radicals 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, convenient preparation and novel electrical and magnetic properties.

Description

technical field 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 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, the Zhang Deqing r...
