Abstract

The invention belongs to the technical field of functional coordination chemistry, and relates to a novel organic-manganese bromide hybrid luminescent material and a preparation method thereof. The chemical formula of the material is C6H16N2MnBr4. The complex is prepared by dissolving trans-2,5-dimethylpiperazine hydrobromide and manganese bromide tetrahydrate in a mixed solvent of acetonitrile and ethanol through a solvothermal method, placing the solution in a reaction kettle, carrying out constant-temperature heating reaction, and after the reaction is finished, naturally cooling to room temperature to obtain the complex. The complex is dissolved in N,N-dimethylformamide, then filter paper is coated with the solution and constant-temperature heating is performed to obtain luminous carbon paper. Preset information can be printed by adopting a CO2 laser marking machine, the retention time of the printing information can be controlled by adjusting the laser power, the printing information is displayed under ultraviolet irradiation, and the printing information can be erased by placing the paper in a certain humidity environment. The luminous carbon paper has good resolution ratio, contrast ratio and cyclic utilization capability, and has good application value and prospect.

Description

Technical field [0001] The present invention belongs to the field of functional coordination chemistry, and is specifically involved in a novel organic-manganese bromide hybrid light-emitting material and a preparation method thereof, which can be used to illuminate copy paper. Background technique [0002] Credable paper can reduce the environmental loss of paper, perform multiple writing and erasing without loss of print information and contrast, so it can be used for anti-counterfeiting and information encryption, and has received extensive attention in recent years. Although various types of smart materials have been used to copy paper, existing organic and inorganic materials still have many problems and limitations, such as the preparation of water-colored dyes, based on cellulose fiber dip iron center transition metal The thermochromic paper printing method of the compound is cumbersome, lacks convenience during the use of conventional paper. [0003] Organic-inorganic hyb...
