Description

A kind of fluorescent material and its preparation method and application
Technical field
The present invention relates to a kind of fluorescent materials and its preparation method and application, belong to organic fluorescence materials field.
Background technique
Off-color material is a kind of color or the special material that absorption spectrum can change with environmental stimulus.According to ring The type of border stimulation or the principle of discoloration are different, and common off-color material can be divided into photochromic, electrochromism, solvation is shown Color, thermochromism, changing color resulting from acid, power mutagens color, friction discoloration, ionization discoloration etc..In numerous off-color materials, light-induced variable Color material is most commonly seen, and this kind of material, which passes through control illumination condition, can realize the transformation of color, has simple, sound Many advantages, such as speed is fast, color change comparison is obvious is answered, thus is widely used in coating, cosmetics, textile printing and dyeing, prevents In the even intelligent door and window design of pseudo- printing, photoswitch, optical storage.
In recent years, in photochromic material, photoluminescence off-color material color not only under visible light or absorption spectrum It can change with illumination condition, fluorescence color or fluorescence spectrum can also change under ultraviolet lighting.This material There is highly important application value in the fields such as bio-imaging, multiple analysis diagnosis, chemical sensitisation, anti-counterfeit printing, thus It is the hot spot of current research.Currently, reported photoluminescence off-color material is mainly based upon the photochromic molecules of conjugation Fluorescence spectrum variation before and after photoisomerization reaction process, color change is relatively single, so that having spy in some pairs of colors It is difficult to preferably utilize in the field of different demand.
Fluorescence resonance energy transfer (FRET) refers to, when the fluorescence emission spectrum and acceptor fluorescence molecule of donor fluorescent molecule Excitation or absorption spectrum when overlapping, the energy of donor fluorescent molecule excitation state can pass to acceptor fluorescence molecule and promote by Body fluorescent molecule shines, while the fluorescence-intensity decay of donor fluorescent molecule itself, or even is quenched completely.The RGB principle of three primary colours Refer to, most colors in nature, can be mixed in a certain ratio to obtain by three kinds of primary colours of red, green, blue；Conversely, Any one colour can be broken down into three kinds of primary colours, corresponding tristimulus value.
Summary of the invention
Inventor by a large amount of experimental studies have found that, designed by reasonable donor and receptor, by fluorescence resonance energy Transfer (FRET) is introduced into three primary colours (red, green and blue) fluorescence system, and guarantees at least one of three components component Receptor is served as, at least one component serves as donor, by the efficiency of fluorescence resonance energy transfer between three components of control, can get Rgb value is adjustable and/or the fluorescent material of Color tunable, or even can get the adjustable full-color fluorescent material of dynamic.Small molecule fluorescent The mechanical property or processing performance of material generally will be poorer than high molecular fluorescent material；Other than photoluminescent property, fluorescent functional is high Molecular physics performance is often depending on the performance of its macromolecule matrix.The polysaccharides natural polymer such as cellulose, starch, chitosan Son is easy to chemical modification, biodegradable, good biocompatibility, in addition, these polysaccharide polymer materials are in nature reserves ten Divide and enrich, thus be ideal functional polymer basis material, the fluorescent functional macromolecule synthesized based on this can obtain While obtaining excellent fluorescence property, retain original good mechanical property, solubility property and processing performance, thus possesses larger Application potential.
