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 luminescent polyacrylic material containing an acrylic functional group polyhedral oligomeric silsesquioxane rare earth complex, and belongs to the field of rare earth polymer composite functional materials. Background technique [0002] Rare earth luminescent materials are widely used in lighting, display, and inspection fields, forming a large industrial production and consumer market scale, and are rapidly expanding to other emerging technologies (such as solid-state dye lasers, anti-counterfeiting, etc.). Because polymer luminescent materials containing rare earth complexes have both the luminescence properties of rare earth ions and the characteristics of good polymer stability and easy processing, they have attracted widespread attention. The research methods can basically be divided into two types: (1) Rare earth small molecules are directly mixed with polymers to obtain doped rare earth polymer fl...
