Embodiment 1

[0027] Eu(DBM) 3 MP and the above-mentioned P5 were dissolved in 10 mL of DMF, and the molar ratio of the two functional groups was 1:1. in N 2 Stirred at 100°C for 48 h under protection, then precipitated in 500 mL of glacial ether, washed several times with ether and hot ethanol, and dried in a vacuum oven at 60°C for 24 h.

[0028] The obtained P5-Eu dilute solution in DMF was placed under 365 nm ultraviolet light, and red fluorescence was emitted.

Embodiment 2

[0030] Others are the same as in Example 1, wherein Eu(DBM) 3 MP exchanged for Tb (p-BBA) 3 MP, the resulting P5-Tb emits green fluorescence under 365 nm UV light irradiation.

Embodiment 3

[0032] Others are the same as in Example 1, wherein Eu(DBM) 3 MP to La (BTZ) 3 MP, P5 is replaced by P20, and the obtained P20-Tb emits blue fluorescence under 365 nm ultraviolet light irradiation.

Abstract

The invention belongs to the technical field of fluorescent material, and particularly relates to a preparation method of an adjustable luminescent rare earth complex-polymer material. The preparationmethod includes: preparing a copolymer which is composed by copolymerizing a monomer comprising anthracene reactive groups, furan reactive groups and the like with a monomer free from the anthracenereactive groups, furan reactive groups or the like, and adopting the copolymer as a macromolecular 'platform'; preparing phenanthroline, with functionalized maleimide, as a ligand, and preparing rareearth complexes which emit primary colors including red, yellow and blue; making use of D-A click reaction among the anthracene reactive groups, furan reactive groups on the macromolecular platform and the functionalized maleimide of the phenanthroline on the rare earth complexes to prepare the adjustable luminescent rare earth complex-polymer material. The preparation method has the advantages that content of rare earth in macromolecules is convenient to control, and is simple to operate, good in reproducibility, capable of realizing large-scale preparation and promising in application prospect.

Description

technical field [0001] The invention belongs to the technical field of fluorescent materials, and in particular relates to a preparation method of a rare earth polymer adjustable fluorescent material. Background technique [0002] In recent years, rare earth complexes-polymer composite fluorescent materials have been widely used in the fields of light sources, sensors, fluorescent probes, and optoelectronics. This is due to the high fluorescence quantum yield of rare earth complexes and good fluorescence monochromaticity. , long fluorescence lifetime and other excellent luminescent properties. As polymers have good processing and molding properties and good mechanical properties, if rare earths are combined with polymers, the use of rare earths can be expanded and various molding requirements can be met. And to precisely control the emission color of fluorescent materials, especially to achieve white light emission, puts forward higher and higher requirements for optical de...
