Problems solved by technology

[0004] In the research on MOFs materials in the prior art, there are many studies on ligands and metal centers, but there are relatively few studies and reports on MOFs materials containing auxochrome and chromophore ligands. Ligand MOFs materials can emit different fluorescence in different polar solvents, so they have a certain indicator function for different solvents

Abstract

The invention discloses a fluorescence discoloration textile in different solvents. The textile is characterized in that a metal-organic framework material is confected to form a solution by using DMF(Dimethyl Formamide), and is spin-coated onto a treated textile through a spin-coating method, so as to prepare and obtain a textile with surface coated with a micro-nano metal-organic framework material. The textile is capable of being fluorescence discoloration in the different solvents. A preparation method of a metal-organic framework comprises the following steps of agitating a transition metal salt, polycarboxylic acid and a blocking agent, so as to obtain a mixed solution, putting into a reaction vessel, using water as a medium and reacting to obtain the micro-nano scale metal-organicframework material. The metal-organic framework material is controllable in size and the prepared and obtained fluorescence discoloration textile is soft in hand feeling, good in washing fastness performance and is sensitive to the indication performance of the solvents.

Description

technical field [0001] The invention relates to a color-variable fabric, in particular to a fluorescent color-changing fabric in different solvents and a preparation method thereof. Background technique [0002] Metal-organic frameworks (MOFs) are typical organic-inorganic molecular crystalline materials, which use metal ions or metal clusters as the center, and small molecular organic ligands as bridging bodies. The coordination between them is assembled under appropriate conditions to form a multidimensional crystalline material. In the past ten years, metal-organic framework compounds, as a new research field, have shown their unique physical and chemical properties and potential in many aspects such as magnetism, fluorescence, nonlinear optics, adsorption, separation, catalysis and hydrogen storage. Great application value. [0003] Although there are many studies on metal-organic framework structure complex materials, there are few reports on the use of this material ...
