Synthesis method of luminescent polyacrylic material containing acrylate functional group polyhedral oligomeric silsesquioxane rare earth complex

Abstract

The invention relates to a synthetic method for a light-emitting polyacrylic material containing an acrylate functional group polyhedronal oligomeric silsesquioxane rare earth complex. The synthetic method comprises: firstly performing coordination on acrylate functional group polyhedronal oligomeric silsesquioxane and a rare earth compound by virtue of coordination chemistry principles; then dispersing the acrylate functional group polyhedronal oligomeric silsesquioxane rare earth complex in an acrylic monomer for in-situ mass polymerization; and finally obtaining the light-emitting polyacrylic material containing the acrylate functional group polyhedronal oligomeric silsesquioxane rare earth complex, wherein the material has good light transmittance, heat stability and a fluorescence property. The synthetic method provided by the invention is simple in synthetic steps, mild in condition, free of any additives and easy to control conditions, and the whole synthetic equipment is easy to construct and is of great innovation, so that industrial production of the light-emitting polyacrylic materials is facilitated.

Description

technical field [0001] The invention relates to a method for synthesizing a light-emitting polyacrylic material containing polyhedral oligomeric silsesquioxane rare earth complexes of acrylate functional groups, and belongs to the field of rare earth polymer composite functional materials. Background technique [0002] Rare earth luminescent materials are widely used in the fields of lighting, display and detection, forming a large scale of industrial production and consumer markets, and are rapidly expanding to other emerging technologies (such as solid dye lasers, anti-counterfeiting, etc.). Because the polymer luminescent materials containing rare earth complexes combine the luminescent properties of rare earth ions with the characteristics of good stability and easy processing of polymers, they have attracted widespread attention. The research methods can be basically divided into two types: (1) Rare earth small molecules are directly mixed with polymers to obtain doped ...

Problems solved by technology

However, the above-mentioned method needs to be coordinated with organic ligands such as acetylacetone or salicylic acid on the one hand, and the preparation process is complicated; on the other hand, the polyhedral oligomeric silsesquioxane of the cage structure used is a Monoamino polyhedral oligomeric silsesquioxane or mercapto polyhedral oligomeric silsesquioxane with a cage structure cannot directly coordinate with rare earth elements, and cannot undergo copolymerization reaction
