Abstract

The invention belongs to the field of a rare earth-polymer composite luminescent material, and specifically relates to a luminescent material of naphthoic acid functionalized polymer and rare earth complex and a preparation method of the luminescent material. In the preparation method, a naphthalene acid ligand with coordination and sensitization dual-function roles on rare earth ions is introduced into a polymer side group; and the ligand not only can form stable polymer-rare earth complex together with the rare earth ions, but also has a large conjugate rigid plane, can greatly enhance energy transfer action of the polymer ligand on the rare earth ions, and enhances the luminescence property. The method disclosed by the invention not only is easy to achieve, but also solves the problems that the rare earth complex in the prior art has dispersion inequality and poor polymer substrate performance.

Description

technical field

[0001] The invention belongs to the field of rare earth-polymer composite luminescent materials, and in particular relates to a naphthoic acid functionalized polymer-rare earth complex luminescent material and a preparation method thereof. Background technique

[0002] Photoluminescent rare earth complexes have good fluorescence monochromaticity, high luminous intensity and high quantum efficiency, and are a kind of luminescent materials with unique properties. However, small molecule rare earth complexes have disadvantages such as poor stability and poor dispersion in polymers, which limit the wide application of rare earth luminescent materials. Polymer materials are widely used due to many advantages such as good physical and mechanical properties, convenient synthesis, easy molding and processing, light weight, low cost, and corrosion resistance. JP2000-154325 (2000) disclosed a method for preparing color-changing rare earth / polymer composite materials w...
