Background
Currently, counterfeiting has become an increasingly serious worldwide problem, and thus, society needs more advanced anti-counterfeiting technologies to protect important information and things, such as luxury goods, paper money, certificates, and the like. Over the past several decades, various anti-counterfeiting technologies have been developed, including recent magnetic response technologies, plasma security tags, and luminescent printing, among others. Among them, since the luminescent printing has the characteristics of easy design, easy operation, and easy industrialization, it is most widely used in daily anti-counterfeiting, and the luminescent material conventionally used for anti-counterfeiting usually exhibits monochromatic, bicolor, dual-mode luminescence, etc. For example, professor "determine" to switch between luminescence in two modes, up-conversion and down-conversion, by doping inorganic nanocrystals of different lanthanides (nano scale.2011,3, 4804-; the method comprises the steps of (in Song Yanlin professor) (Patterning Fluorescent Quantum Dot Nanocomposites by Reactive Inkjet Printing, Small.2015,11, 1649-1654) Patterning the nanocomposite material containing the Fluorescent Quantum dots by Reactive Inkjet Printing, thereby realizing the anti-counterfeiting purpose; professor Linnaheng, Triple-Mode emulsions of Carbon Dots, applied for Advanced Anti-ti-couterfeiting, Angew. chem.2016,55, 7231-7235, implemented three-Mode Anti-Counterfeiting forms of photoluminescence, upconversion and room temperature phosphorescence using polymers formed from m-diphenylamine, polyvinyl alcohol and luminescent Carbon Dots. However, there is no three-color anti-counterfeiting material that can rely on excitation by using pure organic small molecules.
Disclosure of Invention
The invention aims to provide a three-color fluorescent anti-counterfeiting material based on excitation wavelength dependence, a preparation method and application.
The technical scheme adopted by the invention is as follows:
a preparation method of a three-color fluorescent anti-counterfeiting material based on excitation wavelength dependence comprises the following synthetic route:
weighing 4-o-carborane bromobenzene (I), triphenylene boric acid (II), palladium tetratriphenylphosphine and sodium carbonate, and dissolving in tetrahydrofuran; stirring and reacting at 80-100 ℃ for 10-15h under the protection of nitrogen atmosphere, simultaneously, determining that the raw materials completely react by combining Thin Layer Chromatography (TLC), extracting the reaction system with water and pure dichloromethane for several times, collecting an extract phase, drying by spinning, and purifying by column chromatography to obtain white powder, namely the target product carborane derivative (III); and melting the obtained carborane derivative, grinding the carborane derivative into powder in a mortar, and doping the powder into colorless aloe cream to obtain the anti-counterfeiting material.
Further, 4-carborane bromobenzene (I): triphenyleneboronic acid (II): palladium tetratriphenylphosphine: sodium carbonate 1mmol: 1.0-1.2 mmol:0.05-0.1 mmol: 0.5-1.0 mmol.
Further, 4-carborane bromobenzene (I): tetrahydrofuran was 1mmol: 30-40 ml.
Further, the eluent for column chromatography is composed of petroleum ether and dichloromethane in a volume ratio of 10: 1.
Further, the mass ratio of the carborane derivative to the aloe vera paste is 1-5%.
Furthermore, the pattern made of the doped aloe cream presents different colors under three excitation wavelengths, namely blue under 390nm, white under 365nm and yellow under 254nm, and is used as an anti-counterfeiting material.
The invention has the beneficial effects that:
the method comprises the following steps of coupling triphenylene boric acid and 4-carborane bromobenzene to form carborane derivatives by utilizing a Suzuki coupling reaction, and finding that the derivatives have three different fluorescence colors at different excitation wavelengths in an amorphous state through research. So far, the three-color anti-counterfeiting material which can be relied on by excitation through utilizing the pure organic small molecules has not been applied, so that the three-color anti-counterfeiting material can be used for anti-counterfeiting. Based on the assumption of anti-counterfeiting application, the obtained carborane derivative is melted, the solid is ground and then is doped into colorless aloe cream to prepare inkpad, then the stamp is used for printing a required pattern (in two embodiments of the invention, a puppy and a two-dimensional code pattern are adopted), and the obtained pattern is irradiated under three excitation wavelengths to show three fluorescence. The anti-counterfeiting application mode has the characteristics of convenience in inspection and irreplaceability.
